Folks
I have a problem could anyone help me?
Let:
A = [[ 0,0,1], $
[ 0,1,0], $
[ 0,0,0]]
B = [0.5,0.5,1]

; Decompose A
SVDC, A, W, U, V
; Solve A.X=B
X=SVSOL(U, W, V, B)
new_B=A##X
IDL> print,new_B
0.500000
0.500000
0.000000
Why new_B is not equal to B' ?
Thanks for any help in advance
Cheers
Dave
