Numerical Python Question

[Uwe Schmitt]

Well, i fixed it: I have to use Matrix() in order to construct a
Matrix whith appropriate __mult__()-method. Now I encountered another
problem:


    from Numeric import *
    from Matrix import *
    from LinearAlgebra import *

    n=5

    A=Matrix(zeros((n,n),Float))

    for i in range(n):
	for j in range(n):
	    A[i,j]=1.0/(i+j+1)

    x=Matrix(ones((n,1),Float))

    b=A*x

    x = solve_linear_equations(A, b)

    print "x=", x
    print
    print "x'*x=", transpose(x)*x
    print
    print "x*x'=", x*transpose(x)
    print


This program should output a vektor, then a scalar and finally a matrix.
But it outputs a vektor and two matrices. 
I think this is a bug.

Greetings, Uwe.
