Using engine, How to set variable inside to MATLAB function?

Hi all,

I am building c++ algorithm based on matlab algorithm, and I want to compare the results.

I am using matlab engine to set and get variables from matlab workspace.

When I am debugging inside function of matlab I can't set any variables to function workspace,

for example:

% main function
a = 5;
% ...
% ...
% Call to My_Func
My_Func(a)
%...
%...

function  My_Func(a)
% matlab_local_variable = Several calculations
% at this point I want to compare 'matlab_local_variable' with 'c_local_variable'
end

When the debugger is in the main function I can get variable a , and also to add another variables using engGetVariable\engPutVariable.

When the debugger is inside My_Func:

get: In order to get any local variable I copy it to base workspace using:

assignin('base','matlab_local_variable',matlab_local_variable)
% now I can use engGetVariable(pEngine,'matlab_local_variable') from c++

set: When I using engPutVariable(pEngine,"c_local_variable", c_local_variable);

'c_local_variable' apears only in the base workspace and not inside My_Func

How can I compare matlab_local_variable with c_local_variable when the debugger is inside My_Func?

thx
