"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:
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,...)
For more details see:
As the documentation advises, do NOT use global variables, assignin, evalin, etc.
