rand (Matlab function)

Uniformly distributed random numbers and arrays

Matlab/Scilab equivalent

Matlab Scilab

`rand`_(A)

`rand`_(A[,"uniform"])

Particular cases

:B=rand(A) If A is a scalar, then Matlab returns a A*A random

matrix but in Scilab you get a single random value, use rand(A,A) to get the same matrix B. Finally, if A is a matrix, in Scilab, B will be a matrix having the same size as A whereas in Matlab, you get an error message.

:

Note that in Matlab, A can contain complex values (in these cases, only real part of A is taken in account), what Scilab function do not tolerate.

Particular case: To get the state of the uniform generator, in Matlab you have to use s=rand(‘state’) to get 35 current values of the generator, but Scilab equivalent s=rand(“seed”) return only one value.
