For subtracting matrices, their dimension should be equal.
\First write the dimension of the matrix.
\The first matrix is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=32ae6c1e2d883056a2ef453b271e65c5.png\")
The matrix has 2 row and 2 columns, so dimensions of matrix are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=005d206c92b8d7c609a15bd3eef2db91.png\")
.
The second matrix is, ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=665a742b6326a4c80e4b82102d253626.png\")
The matrix has 2 rows and 3 columns, so dimensions of matrix are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=fdb948501136a9fc9590ef122574570b.png\")
