mtlb_int8 - Matlab int8 emulation function
Matlab and Scilab int8 behave differently in some particular cases:
The function mtlb_int8(A) is used by mfile2sci to replace int8(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_int8 calls:
Caution: mtlb_int8 has not to be used for hand coded functions.
