| 00:01 | Paralok, ngi pdiangsngewbha ia phi sha ka Spoken Tutorial halor ka Numerical Interpolation. |
| 00:06 | Ha kaba kut jong kane ka jinghikai, phi sa nang kumno ban: |
| 00:10 | Develop ia ka Scilab code na ka bynta bun jait ki Numerical Interpolation algorithms |
| 00:16 | Khein ia u value bathymmai jong ka function na ki data points ba la ai. |
| 00:21 | Ban record ia kane ka jinghikai, nga pyndonkam |
| 00:24 | Ubuntu 12.04 kum ka operating system |
| 00:27 | Bad ka Scilab 5.3.3 version. |
| 00:31 | Ban pyrshang ia kane ka jinghikai, u ne ka nongpule kidei ban don |
| 00:34 | Ia ki jingtip shaphang jong ka Scilab |
| 00:36 | Bad dei ban tip ia ka Numerical Interpolation. |
| 00:40 | Ban pule ia ka Scilab , sngewbha leit sha ki jinghikai ba iadei kiba don ha ka Spoken Tutorial website. |
| 00:47 | Numerical interpolation kadei ka rukom jong ka |
| 00:51 | Jingshna ia ki data points bathymmai. |
| 00:53 | Hapdeng ki range jong ka discrete set jong ki data points ba la tip. |
| 00:59 | Ngi lah ban solve ia ki jingkhein jong ka interpolation da kaba pyndonkam ia ki numerical methods. |
| 01:05 | Ha Lagrange interpolation, |
| 01:07 | Ngi pass ia u polynomial jong ka degree N – 1 lyngba ki N points. |
| 01:12 | Nangta, ngi wad ia u N order polynomial y of x' bapher uba interpolates ia ki data samples. |
| 01:22 | Ngi ai ia ki natural logarithm values na ka bynta khyndai, khyndai point san bad khatwei. |
| 01:29 | Ngi hap ban wad ia u value jong ka natural logarithm jong khyndai point ar. |
| 01:35 | To ngin solve ia kane ka jingkhein da kaba pyndonkam ia ka Lagrange interpolation method. |
| 01:41 | To ngin peit ia u code na ka bynta ka Lagrange interpolation. |
| 01:46 | Ngi define ia ka function Lagrange ryngkat arguments x zero, x, f and n. |
| 01:53 | X zero udei u interpolation point u bym pat don ba ithuh. |
| 01:57 | x udei u vector uba kynthup ia ki data points. |
| 02:01 | f udei uvector uba kynthup ia ki values jong ka function ha ki data points. ba iadei |
| 02:08 | Bad n udei uorder jong ka interpolating polynomial. |
| 02:14 | Ngi pyndonkam n ban initialize m bad vector N. |
| 02:19 | Ka order jong ka interpolating polynomial' ka batai ia u number jong ki nodes ba la shna. |
| 02:25 | Nangta, ngi pyntreikam ia ka Lagrange interpolation formula |
| 02:29 | Ban wad ia u value jong u numerator bad denominator. |
| 02:35 | Nangta ngi divide ia u numerator bad denominator ban ioh ia u value jong u L. |
| 02:41 | Ngi pyndonkam ia u L' ban wad ia u value jong ka function y ha ka data point ba la ai. |
| 02:48 | Khatduh eh ngi pyni ia u value jong u L bad f of x f(x). |
| 02:53 | To ngin Save and execute ia ka file. |
| 02:57 | Phai sha ka Scilab console' bad solve ia ka problem ba la ai nuksa. |
| 03:02 | To ngin ia define ia u data points vector. |
| 03:05 | Ha ka console, type: |
| 03:07 | x equal to open square bracket nine point zero comma nine point five comma eleven point zero close square bracket. |
