text: The rule for matrix multiplication, however, is that two matrices can be multiplied only when the number of columns in the first equals the number of rows in the second (i.e., the inner dimensions are the same, n for an (m×n)-matrix times an (n×p)-matrix, resulting in an (m×p)-matrix).
text: Addition and subtraction of matrices can only be done if the dimensions are EXACTLY the same.
text: Addition and subtraction of matrices can only be done if the dimensions are EXACTLY the same.
text: That is, the inner dimensions must be the same.
text: Put somewhat differently, the inner dimensions of the two matrices must be the same.
text: When doing so, one can also check to make certain that the inner dimensions are the same, as is required.
