mtlb_eye — Matlab eye emulation function
Matlab and Scilab eye behave differently in some particular cases:
With a scalar input: Matlab eye returns a n x n matrix while Scilab returns a 1.
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:
If A is a scalar
mtlb_eye(A) may be replaced by eye(A,A)
If A is not a scalar
mtlb_eye(A) may be replaced by eye(A)
Caution: mtlb_eye has not to be used for hand coded functions.
