Best Answer
Your example generates
because of the spurious space in
\begin{pmatrix }
andbecause
\om
is not defined.It does only generates the error in the subject line if you ignore those errors and let TeX recover. Subsequent errors are nearly always spurious.
In this case
\cr
is the TeX primitive for a new line in an aligment which is used in the definition of\\
. because the innerpmatrix
did not start because of the first error, TeX takes the\\
as ending the outer alignment row inside the group, which is an error.
