What varibles? what functions? post an example

[Rightia Rollmann]

How to see variables in_1, out_1, and internal in the Workspace?

function [ out_1 ] = test( in_1 )

out_1 = in_1 + 1;

internal = [ 1 2 ];

end

[Azzi Abdelmalek]

function out_1 = test( in_1 )
global internal
out_1 = in_1 + 1;
internal = [ 1 2 ];

Save this function as test.m then in Matlab Windows command type

global internal
in_1=10  % set a value to in_1
out_1 = test( in_1 )
internal

@Rightia Rollmann: rather than learning bad programming practices (using globals), you should simply learn to use the debugging tools, or passing variables properly.

[Azzi Abdelmalek]

function y=som(x,y,z)
global a b
  a=x*y
  b=y^z
  y=a+b

When you call the function som

global a b  
y=som(1,2,3)
