Show variable value of subfunction in workspace.

Please suggest how to show subfunction variable value in the worksapce that are called in the main function. When i run main function workspace shows only main function's variable value, not shows variable value that are in the subfunction.

"When i run main function workspace shows only main function's variable value, not shows variable value that are in the subfunction."

That is exactly what should happen. Every function has its own independent workspace, and any variables inside that workspace are only available there... unless you explicitly pass them to another workspace. See:

https://www.mathworks.com/help/matlab/matlab_prog/base-and-function-workspaces.html

The easiest and most efficient way to pass values from one workspace to another is to pass them as input/output arguments, e.g. to define the function with the required arguemnts:

function [AA,BB,CC,..] = myfun(XX,YY,ZZ,...)

and call it with those arguemnts:

[outA,outB,outC,...] = myfun(inX,inY,inZ,...)

As the documentation advises, do NOT use global variables, assignin, evalin, etc.
