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