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=ac5d6352dcd1112f6c2ecf2f4d791531.png\")
and the number of the columns in The matrix A is 3.
The dimensions of the matrix B are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=1fbec063524eac061c759ec9a4aa01f9.png\")
and the number of the rows in the matrix B is 3.![\"\"](\"/userfiles/image/steps_images/step2.JPG\")
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=005d206c92b8d7c609a15bd3eef2db91.png\")
