RE: [WM]: Pseudorandom matrix in Matlab

["Chuck Rewood" <riwut@nii.itb.ac.id>]

Thanks for all ppl. reply to me,

but I need zero mean matrix, so that numbers of -1 equal to numbers of 1.
I've tried 
	randint(M,N) 	(in Matlab 6.12)
but the documentation said that that command will generate with 'equal
probability'  not 'equal numbers of -1 or 1'

any clue of syntax please ?

Best regards,

Rewood

Hi,
   you don't need any work, just use Matlab command. For example
floor(3*rand(M,N))-1
to make M by N matrix as you want.
