Use parentheses so that the assignment occurs before the MatrixForm is applied.

(m = {{1, 2, 3}, {4, 5, 6}}) // MatrixForm
Transpose[m]

this just does nothing. it simply prints back what I typed with
m in MatrixForm but does not actually do the transpose.

But when I do

m = { {1, 2, 3}, {4, 5, 6} }
Transpose[m]


it works.

It seems that the function Transpose does not like to accept a
list in 'MatrixForm' ?

I use a MatrixForm to see the matrix better. Does this mean one have
to removed the MatrixForm each time before calling Transpose?
