mtlb_zeros

Matlab zeros emulation function

Description

Matlab and Scilab zeros behave differently in some particular cases:

  • With a scalar input: Matlab zeros returns a n x n matrix while Scilab returns a 0.

The function mtlb_zeros(A) is used by mfile2sci to replace zeros(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_zeros calls:

  • If A is a scalar mtlb_zeros(A) may be replaced with zeros(A,A)

  • If A is not a scalar mtlb_zeros(A) may be replaced with zeros(A)

  • mtlb_zeros(size(A)) may always be replaced with zeros(A)

Caution: mtlb_zeros has not to be used for hand coded functions.
