Matlab hold emulation function
There is no Scilab equivalent function for Matlab hold but there are equivalent instructions.
The function mtlb_hold(flag) is used by mfile2sci to replace hold flag when it was not possible to know what were the inputs 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_hold calls:
Caution: mtlb_hold has not to be used for hand coded functions.
