mtlb_lower - Matlab lower emulation function
Matlab lower(A) and Scilab convstr(A,"l") behave differently in some particular cases:
The function mtlb_lower(A) is used by mfile2sci to replace lower(A) 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_lower calls:
Caution: mtlb_lower has not to be used for hand coded functions.
