Matlab rand emulation function


Matlab and Scilab rand behave differently in some particular cases:

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

The function mtlb_rand(A) is used by mfile2sci to replace rand(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_rand calls:

  • If A is a scalar mtlb_rand(A) may be replaced by rand(A,A)

  • If A is not a scalar mtlb_rand(A) may be replaced by rand(A)

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


  • V.C.
