How to call a function which is in another program MATLAB

Question

I write this in my main programm

[C,rows,cols,entries] = Matrix('C.txt')

Matrix fuction is in another program Matrix.m and I want to call it.

I get this error :

Undefined function or variable 'Matrix'.

Error in (line 19)

[C,rows,cols,entries] = Matrix'C.txt')

Can you please tell me how to fix it ?

Answer 1

It is possible that your file and function are not in the same folder. If you do not want the file and function in the same folder, you can use addpath to add search path of your function path or folder.
