Time Narration
00:00 Ngi pdiangsngewbha ia phi sha ka spoken tutorial halor ka Plotting 2D graphs bad ka Scilab.
00:04 Ngi shim ba ka Scilab la dep install ha ka computer jong phi , ngin ia kren shaphang “plots ”ha Scilab.
00:10 Scilab ka ai shibun ki lad ban create bad customize bun jait ki 2D bad 3D plots.
00:15 Ki common charts ba bun ba ka Scilab ka lah ban shna kidei: x-y plots, contour plots, 3D plots, histograms, bar charts bad kiwei kiwei
00:24 Mynta plie ia ka Scilab console window jong phi.
00:28 Ngan pyndonkam ia ka Plotting.sce file ban cut bad paste ia ki commands.
00:34 Ban lah ban plot, ngi donkam ia ka set jong ki points. To ngin create ia ka sequence jong ki equally spaced points.
00:39 Kane lah ban leh da ka linspace command kaba create ia u linearly equally spaced vector.
00:45 Kum ka nuksa,
00:48 x udei u row vector ryngkat 5 points linearly equally spaced hapdeng 1 bad 10.
00:57 Kumjuh ruh, y udei u row vector ryngkat linearly equally spaced 5 points hapdeng 1 bad 20.
01:08 Kham bun ki jingtip halor ka linspace lah ban ioh na ka Help documentation.
01:14 Ngin plot ia ka graph bad ki arguments x bad y da kaba pyndonkam ia ka plot function.
01:19 Kane ka iasyriem bad ia kaba pyndonkam ha ka matlab.
01:23 plot(x,y) ka create ia ka graph jong x verses y kumba phi iohi.
01:31 Phi iohi ba ka Graphics window la labeled kum '0'.
01:36 Ngin plie sa kawei ka graphic window da kaba pyndonkam ia ka xset function.
01:41 Ngan khang noh ia kane.
01:43 Cut ia ka xset function, paste ha Scilab, nion Enter.
01:50 Phin iohi ia ka Graphic window number 1.
01:54 Kynmaw ba ki artylli ki arguments la passed sha kane ka function kata ka 'window' bad 1.
02:03 Ka graph ba bud yn sa plot ha kane ka window.
02:06 Na ka bynta ka Scilab, plot2d kadei ka native function ba pyndonkam ban plot ia ki 2d graphs.
02:14 plot2d command ka plot ia ka graph jong x verses y kumba phi iohi.
02:26 Phi iohi ba don u argument balai ba kyrteng 'style'.
02:31 style argument udei optional. La ju pyndonkam ban pynpher ia ka jingwandur jong ka plot.
02:36 Na ka bynta ki positive values jong style, ka curve kadei plain ryngkat kiwei ki rong ba bun kum green na bynta 3 ha kane ka bynta jong ngi.
02:44 Ka default value jong style kadei 1.
02:46 Pyrshang ban plot ia ki graphs na ka bynta ki negative values bad peit hi ia ka jingpher ha ka jingwandur.
02:51 Kumjuh ruh ngi lah ban set ia ki start points bad end points na ka bynta x bad y axes da kaba pass ia u argument basaw.
02:57 La ju khot ia u rect. Kumba phi iohi,
03:07 Ngi don x axis ba sdang na 1 haduh 10 bad y axis na 1 haduh 20.
03:14 Ka order jong ki argument ha ka rect command kadei xmin,ymin,xmax bad ymax.
03:24 To ngin pule mynta shaphang ka title,axis bad legends
03:28 Ban configure ia ki labels sha ka axis bad title sha ka plot ngi lah ban pyndonkam ia ki commands title, xlabel and ylabel.
03:38 Ngan cut ia kane ka set jong ki commands bad paste ha ka console . Nion Enter.
03:45 Phin iohi ba ka graph lah dep labeled x sha ka x-axis,y sha ka y-axis bad ka title jong ka graph kadei ‘My title’
03:58 Phi lah ban kwah ban configure ia ka title bad axes jong ka plot ha kawei ka command ha ka jaka jong 3.
04:04 Na ka bynta kane ka kam ngi pyndonkam ia ka xtitle command ryngkat bad baroh 3 tylli ki arguments.
04:11 Ngan cut ia kane ka command , paste ha scilab , “Enter”
04:18 Mynta phi iohi ba ka x-axis label kadei X-axis, Y axis bad ka title kadei 'My title'.
04:26 Ka clf() function kaba nga type mynta, kan clear ia ka graphic window kumba phi iohi.
04:36 Ka iarap ha ka por ba plot ia ki graphs bapher bapher ha ka juh ka graphic window.
04:41 Ngan khang noh ia kane ka window.
04:44 Teng2 ngi donkam ban ianujor ia artylli ki sets jong ki data ha kajuh ka plot , kata, kawei ka set jong x data bad artylli ki sets jong y data.
04:51 To ngin peit ia kawei ka nuksa na ka bynta kane, Ngan scroll shapoh.
04:56 Ngin define ia ka x-axis points ha u row vector “x” da kaba pyndonkam ia ka linspace command.
05:03 To ngin define ia ka function.
05:05 y1 = x square.
05:07 plot x verses y1.
05:10 Define ia kawei ka function y2 = 2 x square.
05:15 plot x verses y2.
05:17 Ngin ai ruh ia ka label bad ka title sha ka graph jong ngi.
05:22 Phin iohi ba ngi don ia kiba la passed lang “o-” bad “+-” commands sha ka plot function, ban pynkylla ia ka jingwandur jong ka curve.
05:33 Kine ki arguments kim dei ki bynta jong ka plot2d function.
05:37 Kine lah ban pyndonkam tang bad ka plot function.
05:41 Ngan copy ia kine ki set jong ki commands bad paste ha ka Scilab console.
05:49 Phi iohi ia ka graph.
05:51 Hato kam dei ka jingiarap ba biang bha ban tip kano ka curve ka don jingiadei bad kano ka function?
05:56 Kane lah ban iohi da kaba pyndonkam ia ka legend command kumba phi iohi.
06:08 “o-” curve u thew ia ka function y1=x square bad “+-” curve u thew ia ka function y2=2*x^2 (y2=2x square)
06:19 Ngan khang noh ia kane ka graphic window.
06:22 Ngin ia kren mynta shaphang ka plot2d demos bad subplot function.
06:28 Scilab ka ai ia ki demos na ka bynta baroh ki functions ba kham donkam.
06:31 Demosjong ka plot2d lah ban peit lyngba jong ka demonstration tab.
06:39 Nion ha Graphics, click 2D bad 3D plots bad jied ia kawei ka demo na ki demos ba bun ba la ai.
06:51 Ngan nion ha plot2d.
06:54 Phi iohi ia ka demo graph.
06:55 Une u code na ka bynta ka graph lah ruh ban iohi da kaba nion ha u view code button hangne.
07:02 Kane ka link kam plie ha ka Mac OS tangba ka treikam ha Windows bad Linux.
07:07 Wat la katta ha ka Mac u code lah ban peit lyngba jong ka directory.
07:12 To ngin phai sha ka terminal.
07:15 Ia mynta nga don ha ka 'demos' directory jong ka Scilab 5.2 kumba la pyni.
07:21 Ka path bapura sha kane ka directory la pyni hangne.
07:27 Ngin type ls ban iohi ia ka list jong ki demos ba don , kumba phi iohi hangne.
07:36 Nangta ngin jied ia ka 2d_3d_plots directory bad nion “Enter”
07:46 Type ls sa shisien ban iohi ia shibun ki demo code ba don ha ka 'sce' files.
07:55 Ngin peit ia u code na ka bynta ka demo kaba ngi la dep peit hashwa.
08:00 Type more plot2d.dem.sce bad nion Enter.
08:11 Hangne phin iohi ia u code na ka bynta ka demo graph jong ka plot2d function.
08:18 Ngan khang noh ia ka terminal.
08:21 Ngan khang noh ia ka demo graph bad ka demo window.
08:26 Ha kajuh ka rukom phi lah ban iaid lyngba jong kiwei ki demos bad tih bniah ia ka Scilab.
08:29 To ngin ia kren mynta shaphang ka subplot function.
08:33 Ka subplot() function ka phiah ia ka graphics window sha ka matrix jong ki sub-windows.
08:37 Ban batai ia kane ka function ngin pyndonkam ia ki demos na ka bynta ban plot ia ka 2D graphs ha ka Scilab.
08:43 Kum ka nuksa, type plot2d ha ka console jong phi bad peit ia ka demo plot na ka bynta kane ka function.
08:58 Ngan khang noh ia kane ka window.
09:00 Ka “subplot command” kan phiah ia ka graphics window sha ka '2 by 2' matrix jong ki sub-windows ba la kdew da ki artylli ki arguments ba nyngkong ha ka subplot command.
09:10 U argument balai u kdew ia ka current window ha kaba ia ka plot yn sa plot.
09:15 Ngan execute ia baroh kawei ka set jong ki commands da kaba copy ia ka sha ka scilab console.
09:24 Phi lah ban iohi 4 tylli ki plots ha kawei ka plot window.
09:28 Ka plot ba la ioh lah ban save kum ka image ha ka computer jong phi.
09:32 Nion ha ka graphic window, leit sha ka “File” menu, jied “Export to”.
09:39 Ai ia ka title ba biang ia ka plot jong phi.
09:50 Jied ia ka destination folder ban save ia ka file jong phi.
09:54 Jied ia ka file format ha kaba phi kwah ba ka image kan paw.
09:59 Ngan jied ia ka JPEG format bad nion “Save”
10:05 Browse lyngba ka directory ban plie ia ka image bad pynshisha ialade ba lada la dep save ne em.
10:11 Bad da kane ngi la poi sha kaba kut jong ka spoken tutorial halor ka Plotting in Scilab.
10:15 Don shibun kiwei pat ki functions ha Scilab kiba ngin sa iapeit ha kiwei pat ki spoken tutorials.
10:20 Iai peit ia ki Scilab links.
10:22 Spoken Tutorials kidei shibynta jong ka Talk to a Teacher project, bad la kyrshan da ka National Mission on Education lyngba ka ICT.
10:29 Kham bun ki jingtip halor kine ki don ha ka link ba la ai harum.
10:32 Nga i Meboreen na Shillong nga pynkut ia kane .Khublei Shibun.
