How to make the contents available in a function for calculation in another function

Dear all,

Thanks for your time.

I am working on a function as an example:

function [a]=b a=[1 2 3] end

and I would like to make this 'a' matrix available for calculation in another function,which as

function [e,f]=d c=a+b e=c*1 end

However, I always received an error message as Undefined function or variable 'a'.I don't really understand why this happened and how to solve this problem.

Thank you very much.

You need to pass a to the other function then.

First function:

 function  [a] = b
    a = [1 2 3];

Second function:

 function [e,f] = d(foo); %You need to pass an argument to this function
     c = a + foo; %or whatever
     e = something;
     f = something_else + a;

Then in your script you call the function d as follows:

 [e,f] = d(b);
