Programs or funtions in Matlab can port to my TI Nspire CX CAS ?

[Walter Carrillo]

Hello, I am a student and I am taking programming class. I have a TI Nspire CX CAS

I would like to program my calculator with my  scripts develop in Matlab. How I can do in this case such a function?

example function in Matlab:

function [rad,ang]=rec2pol(x,y) 

 rad=norm(x,y);

 ang=atan(y/x);

end

sorry my English is bad but it does need to learn something new

Try Insert > Program Editor > New

Name it, say rec2pol.

Choose Function (rather than Program)

Define Function rec2pol(x, y)

Func

Local rad, ang                    (A function can only have local variables, so it leaves no trace)

 rad := norm([x,y])              (Norm takes as its argument a vector or matrix, hence the square brackets)

 ang := arctan(y/x)             (Note the use of ":=" to define variables)

return {rad, ang}                 (A function must return a single argument, so here put both values in a list)

endFunc

Hi Walter,

Wow.  I hope this doesn't sound like a "blow off" insignificant answer, but there's really too much to explain here.  Have you read the Nspire manual and Reference Guide?  Those are excellent places to start.  They will get you started on how to write a program/function and how to make a library (useful!), and the reference guide gives specifics on how to use all of the functions.  These can be downloaded from the Nspire website.

Hope this helps.  If you have a more specific question, please ask and we can probably help you.
