Multiplication of two matrices possible if the number of columns in the
\first matrix equals the number of rows in the second matrix.
\The dimensions of the matrix M are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=9150b5bf157cf6dbc36d0334187ffde0.png\")
and the number of columns in
the matrix M is 1.
\The dimensions of the matrix N are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=77eda1f4c151406f7beb6f168a286609.png\")

The number of columns in the matrix M is not equals the number
