Hi everybody,(adsbygoogle = window.adsbygoogle || []).push({});

Last time I was here I was asking about finding roots but many things have progressed. Anyway I have another problem now.

I have a linear system of equations which I'd like to solve: A.X==B

And I tried two things: get the inverse of A and multiply it with B and also use LinearSolve. Both gave me the same result so far so good.

The weird part happened when I did the same thing in MathCad. I used the same system of equations and the same everything. I tried the two methods and I got different solutions for X.

But the only way to get the two programs to agree (I did this as a fluke) is if in Mathematica I do: X=B.Inverse[A] and in MathCad i have X=Inverse[A].B.

I don't get it. What is this? What is it that I don't see?

I would very much appreciate if someone can clarify this for me.

Cheers,

Lucian
