I used to typeset an augmented matrix this way:
\m{\pMat{1,7,-6,\vrule,-4;3,-4,7,\vrule,13;4,3,1,\vrule,9}}
But this no longer works.
Though I can get over this with
\m{\pMat{1,7,-6,¦,-4;3,-4,7,¦,13;4,3,1,¦,9}} ,
I find the result from the old way looks nicer.
Is the using of \backslash vrule within mathmatrix gone for good?
