Matlab setstr emulation function
Matlab setstr and Scilab ascii behave differently in some particular cases:
The function mtlb_setstr(A) is used by mfile2sci to replace setstr(A) when it was not possible to know what was the input while porting Matlab code to Scilab. This function will determine the correct semantic at run time. If you want to have a more efficient code it is possible to replace mtlb_setstr calls:
Caution: mtlb_setstr has not to be used for hand coded functions.
