Time Narration
00:01 Ngi pdiang sngewbha sha ka spoken tutorial ha ka Functions and Types.
00:06 Ha kane ka jinghikai, ngin ia pule: Kumno ban define ka function.
00:12 Kumno ban pyndonkma ka algorithm. Kumno ban define ka type.
00:17 Ban record kane ka jinghikai, nga pyndonkam OpenModelica 1.9.2 bad Ubuntu operating system version 14.04
00:27 Tangba, kane ka rukom ka iasyriem ha Windows, ”Mac OS X” lane FOSSEE OS.
00:35 Ban sngewthuh kane ka jinghikai phi donkam ban tip kumno ban define ka class ha Modelica.
00:41 Phi donkam ka jingtip jong ki functions ha kano kano ka programming language.
00:46 Ki jinghikai pre-requisite lah dep batai ha ka website ka jong ngi. Sngewbha sa pule ia ki.
00:52 To ngin ia kren ia ka function mynta.
00:55 function ka dei ka class kaba kyrpang ba lah ban shim ki input bad return output.
01:01 Ka don ki algorithm section.
01:04 Ka function kam lah ban don ki equations bad kam lah ban simulate.
01:10 Ka syntax jong ka “function”kadei kumba la pyni.
01:15 Mynta to ngin ia thoh ka function ba kyrteng polynomialEvaluator kaba shim x kum ka input bad kan return f(x) = a x (squared) (plus) b x (plus) c ha kaba a=1, b=2 bad c=1 kum ka output.
01:36 polynomialEvaluator file lah ban ioh na ka website ka jong ngi.
01:40 Sngewbha download bad save baroh ki files ba lah ban ioh na Code Files link.
01:46 Ban pyni polynomialEvaluator function, to ngan leit sha OMEdit.
01:52 OMEdit mynta ka lah plié ha Welcome prespective.
01:56 Phi lah iohi tang ka liang jong ka OMEdit window naduh ba nga lah zoomed hapoh.
02:02 Ngan pyni ia phi ka jaka kaba kham biang da kaba kynriah ka window lada donkam.
02:09 Ban plie ka files kaba phi lah dep download, klik ha Open Model/Library File tool.
02:16 Nga lah dep save baroh ki files ha ka folder.
02:19 To ngan jied lang ia ki bad klik ha open.
02:24 Lada ngi lah dep save kine ki file ha ki folder kiba pher, phi lah ban plié man la kawei la ka jong.
02:31

Kynmaw ba kine harum classes lane functions mynta lah plié ha OMEdit: bouncingBallWithUserTypes , functionTester ,multipleFunctionTester, multiplePolynomialEvaluator bad polynomialEvaluator.

02:51 Ban plie polynomialEvaluator function bad view iaka, Right-klik hau icon ha Libraries Browser bad jied View Class.
03:02 Lada ka function ka plie ha ka Text View, plie ia ka ha ka Text View.
03:08 Ka kyrteng jong kane ka function ka dei polynomialEvaluator kumba ngi lah dep ia kren.
03:14 x u dei u real variable.
03:17 input ka dei ka keyword kaba pyndonkam ban kdew input variables.
03:22 Kumjuh ruh, output ka dei ka keyword kaba dei ban kdew output variables.
03:28 “fx” udei u real variable uba ieng ia u f(x).
03:33 Uno uno u variable lane parameter ubym dei u input lane output la kdew da kaba pyndonkam protected.
03:42 a u dei real parameter bad u value jong u udei 1.
03:47 Ki values jong u a, b bad c lah dep iakren lypa ha ki slides.
03:53 Sngewbha kynmaw ba a, b bad c kidei ki “protected” parameters.
03:59 Algorithm ki ieng na ka bynta ka jing sdang jong ka algorithm section jong ka function.
04:05 Algorithm section ka lah ban don ki assignment tang ki statements.
04:10 Kane ka sign ka kdew ia ka assignment.
04:14 Haka assignment statement ka value jong ka liang kamon la assigned sha ka liang jong ka liang kadiang.
04:20 Ka liang kadiang kumba ka dei ka expression ka bym tip.
04:25 Ha kane ka case fx udei u variable bym tip.
04:29 Ka value jong ka expression sha ka liang kadiang hangne lah ban khein lada u value jong u x ym tip.
04:36 x u kumba u long u pass ka input kum argument sha u function haba u lah shah khot.
04:43 Mynta to ngin ia peit kumno ban call ia ka function da kaba pyndonkam function Tester class.
04:49 function Tester icon lah dep iohi lypa ha ka Libraries Browser namar nga lah dep plié lypa ia ka.
04:56 Ban plié ia kane class, klik arsien ha une u icon.
05:01 Kane ka dei kawei na ka rukom ban peit ia ka “class”.
05:05 Phi lah ruh ban right klik ha u icon bad jied View Class.
05:11 “z” u dei u “real” variable.
05:14 polynomialEvaluator function lah khot bad ka input argument jong 10 units bad la equated shaz.
05:23 Ka input value(varaible) jong u polynomialEvaluator kata ka dei x u shim ia ka value jong 10 units.
05:31 Mynta to ngin ia simulate kane ka class.
05:34 Ban simulate kane ka class phi lah ban right klik ha functionTester icon ha Library Browser bad jied Simulate.
05:45 Ka class mynta lah dep simulate.
05:47 Phi lah ruh ban pyndonkam ka Simulate button ha ka toolbar ban simulate ka class.
05:53 Mynta to ngan pyni ia phi ka Plotting prespective da kaba kynriah lut sha ka OMEdit wondow sha ka kadiang.
06:00 Jied z ha ka variables browser
06:04 Kymnaw ba ka value jong u z u equal sha u value jong f(x) ha x = 10.
06:12 Mynta to ngan nym jied z bad delete kane ka result.
06:18 To ngan leit phai biang sha ka Modeling prespective.
06:21 Klik ha polynomialEvaluator tab ba sha jrong.
06:25 Kynmaw ba ka polynomialEvaluator function ka don tang kawei ka output variable.
06:31 Mynta to ngan pyni ia phi kumno ban output ar lane bun ki variables da kaba pyndonkam ka function.
06:38 Nga lah dep shna ka function ba kyrteng multiplePolynomialEvaluator kaba don artylli ki output variables.
06:45 Before viewing that function let me close the tabs of PolynomialEvaluator and FunctionTester.

Shuwa ban peit kitei ki “function” to ngan khang ka tab jong “PolynomialEvaluator” bad “Function Tester”.

06:54 Namar ka Libraries Browser kam da paw, to ngan shift ia ka window sha ka kamon.
07:01 Klik arsien ha multiplePolynomialEvaluator, multipleFunctionTester bad bouncingBallWithUserTypes.
07:11 Shift biang ia ka window sha ka jaka ba dei.
07:15 Leit sha multiplePolynomialEvaluator tab.
07:19 Kane ka function ka iasyriem bad ka polynomialEvaluator function lait noh na ka bynta ka additional output variable.
07:27 An output variable name gx has been declared.

Ka “output” variable ka kyrteng “gx” lah dep declare.

07:32 gx la assigned u value jong a x (squared) (minus) b x (plus) c
07:38 Ka order ha kaba ka output lane input variables ba lah declare ki long kongsan.

13:10 Lada phi don kano kano ka jingkylli ha kane ka spoken tutorial, sngewbha wan jong i aka website.
13:15 Ngi coordinate codeing jong ki nuksa ba lah dep khein jong ki kot kiba paw. Sngewbha wan jngoh sha ka website ban tip kham bun.
13:23 Ngi iarap ban migrate ki commercial simulator labs sha OpenModelica.
13:29 Spoken Tutorial Projectla kyrshan da ka NMEICT, MHRD, sorkar India.
13:36 Ngi ai khublei ia ka kynhun jong ki nongshana jong ka OpenModelica ka jign kyrshan ka jong ki.
