mtlb_randn

Matlab randn emulation function

Description

Matlab rand and Scilab rand(...,”normal”) behave differently in some particular cases:

• With a scalar input: Matlab randn returns a n x n matrix while Scilab rand(...,”normal”) returns a scalar.

The function mtlb_randn(A) is used by mfile2sci to replace randn(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_randn calls:

• If A is a scalar mtlb_randn(A) may be replaced by rand(A,A,”normal”)
• If A is not a scalar mtlb_randn(A) may be replaced by rand(A,”normal”)

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