scilab

Cannot call a simple function in scilab?

lets say I have written a function for adding two numbers.

function [result] = add_twonum(a1,a2)

result = a1+a2;

endfunction

in the main file, when I call 

result = add_twonum(1,2)

I expect result = 3 .

However it says

!--error 4

Undefined variable: add_twonum

Please help me. I have used Matlab a lot but never scilab. I tried every possible way I know of. like changing current directory etc etc.

Solution

  • In the main file, you need to execute the function first, with

    exec('add_twonum.sci');

    assuming add_twonum.sci is the file which contains your function. Then you can call the function:

    result = add_twonum(a1,a2);
