Question

I have created a function (lets call it function A) in MATLAB that uses 'for loop' to create a 3*4 matrix. I am creating another MATLAB function (lets call it function B) that has absolutely no relation with function A but needs to use the matrix from function A.

How do I call only the matrix from function A to function B such that as this matrix changes in function A it triggers corresponding changes in function B as well?

Is there a way I can save the matrix in function A after the 'for loop' such that I can call the matrix anywhere else I choose?

Thanks

Answer 1

Lets take an example that You have created a matrix 'Y' in function A. You can take it as return

syntax

function [Y] = Function_A()

%% function body%%

end

then on main window you can write

C=Function_A();

so the matrix on which you have performed operation will be returned by Function_A and will get store in C;

now you can pass this matrix in Function_B by writing

Function_B(C);

for full example i am creating two function with same name as given in the problem

function[Y]= Function_A() Y=eye(4); end

above created a function with name Function_A which create a matrix Y which is 4*4 identity matrix;

and below is the function with name Function_B which will then calculate the determinent of that matrix and store it in 'r' and then return it. below a picture attached see how to use it

function[r]= Function_B(C) r=det(C); end

Hope u understood it
