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 A are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=788e9b0d0cba2a5fab42b21b55980377.png\")
and the number of columns in the matrix A is 2.
The dimensions of the matrix B are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=77eda1f4c151406f7beb6f168a286609.png\")
and the number of the rows in the matrix B is 2.

The number of columns in the matrix A equals the number of rows in the matrix B.
\So, matrix product AB is possible.
\Its dimensions are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8bbef7dd1c516fb5496136a421553937.png\")
