[Numpy-discussion] RandomArray - random

Your reference to random is not fully qualified so I suppose you could
be picking up some other random. But I just tried
RandomArray.random((2,3)) and it worked fine.

BTW you could just do 2.0*random((n,m))-1.0.

Hi,

I tried to produce a random matrix say Q (2ndof \times nsamp+1) with
Numpy 20.2 and Python 2.1.1 (#1, Sep 24 2001, 05:28:47) [GCC 2.95.3
20010315 (SuSE)] on linux2 Type "copyright", "credits" or "license" for
more information.

Traceback (most recent call last):
  File "modal.py", line 192, in ?
    Q = 2.0*random((2*ndof,nsamp+1))-ones((2*ndof,nsamp+1))
TypeError: random() takes exactly 1 argument (2 given)

Does it require a new syntax to obtain a matrix consisting of uniformly
distributed random numbers in the range +/- 1 ?

Nils
