mtlb_false

Matlab false emulation function

Description

There is no Scilab equivalent for Matlab false. However, Scilab zeros returns a result interpreted in an equivalent way for Scilab.

Matlab false and Scilab zeros behave differently in some particular cases:

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

The function mtlb_false(A) is used by mfile2sci to replace false(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_false calls:

• If A is a scalar mtlb_false(A) may be replaced by zeros(A,A)
• If A is not a scalar mtlb_false(A) may be replaced by zeros(A)

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