The following matrix is not displaying all elements in each row on the same line, the last element in each row is getting pushed to the next line. If I delete the last element then the matrix displays correctly. I am getting this error when I compile -
You have given more \span or & marks than there were in the preamble to the \halign or \valign now in progress. So I'll assume that you meant to type \cr instead.
