mtlb_eye

Description

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.
