> Problems can occur if you launch too many Excel instances carelessly.

See? Greg is a very wise man. It's been a while since I mentioned it, but
there is some evil associated with CreateObject: it will create a new
instance of the server. GetObject on the other hand will reuse an existing
server if possible, and if the server isn't running it will start it.

If you're doing a lot of Excel stuff and finding it rather more than you're
willing to put up with check out his add-in.

Not familiar with this division of a matrix by a column vector. Do you mean
array(A[0,0]/B[0], A[0,1]/B[1}... A[3,3]/B[3] ???

Can you do that, divide a 4x4 by a 4x1???? How do you get the inverse of B,
doesn't B need to be square?

Subject: [vrf] Matrices and matDivide

Hello,

I am going to use gauss elemination a two matrices (MATLAB expression X =
AB)

I have tried the built-in function MatDivide and a MATLAB Script. The input
is A(4x4 matrix) and B(4x1 matrix) and the output is X. But I can't get any
of the two methods to work.

A = [262144, 4096, 64, 1; 166375, 3025, 55, 1; 97336, 2116, 46, 1; 46656,
1296, 36, 1]

B = [70; 60; 50; 40]

X = AB

Is there anyone who has some experience in using math at matrices in Agilent
Vee?

Best regards,
Susanne Jrgensen
