Do you want to create a temporary variable ? Or a mask parameters ?

In Mask Initialization function
aVal = str2double(get_param(gcbh, 'a')); % a is existing mask parameter
bVal = str2double(get_param(gcbh, 'b')); % b is existing mask parameter
set_param(gcbh, 'c', num2str(aVal+bVal)); %c is existing mask parameter
