mtlb_rcond — Matlab rcond emulation function
Matlab and Scilab rcond behave differently in some particular cases:
With empty matrix: Matlab rcond returns Inf and
Scilab rcond returns []
The function mtlb_rcond(A) is used by
mfile2sci to replace rcond(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_rcond calls:
If A is not an empty matrix,
mtlb_rcond(A) may be replaced by rcond(A)
Caution: mtlb_rcond has not to be used for hand coded functions.
