For the program, for example:
function output = input(n)
global SAVER;
SAVER = zeros(n,n,20);
*other code here*
output = SAVER(:,:,5)
When this is run in the command window (by input(5) for example), the variable ans appears in the workspace.
However, I was under the impression that because SAVER was declared as a global variable, it would also be saved globally and would be accessible from the workspace.
However, when I type SAVER(:,:,2) for example in the command window after running input(n) I get the error message Undefined function or variable 'SAVER'.
Is it possible to access the different elements in SAVER from the command window after running the function, and is this not what a global variable does?
