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=25f1760d6c21ccc5642b0366920242e0.png\")
and the number of columns in the matrix A is 1.
The dimensions of the matrix B are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=e454e7810ed6d7941bedf75b6f1bae9a.png\")
and the number of the rows in the matrix B is 1.

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=84fcac3ea0721df4603ad930be3ebe56.png\")
