Hi everyone!
I'm running Mathematica 3.1.x on Windoze 95. Here's a simple question
that has been bothering me recently.
Suppose I define:
a={{1,2},{3,4}};
In this case,
Inverse[a]
gives back the expected result
{{-2,1},{3/2,-1/2}}
However, suppose I now define
b=a//MatrixForm
and now type
Inverse[b]
I *don't* get back any answer as before, but just my input
Inverse[(2 3)]
[(4 5)]
(The above is supposed to be a matrix!). Anyways, why is this?!? Other
operations also fail to work in the same manner, such as Det,
Transpose, Eigenvalues, Eigenvectors, etc.
Is this a bug with Mathematica's front end? Any help with this would be
greatly appreciated!
Thanks,
Mike
