Matrices Subtraction

We can calculate with matrices, just as we do arithmetic with numbers. We can matrices calculate if we follow the rules for their arithmetic.

Because of this similarity, it is useful to distinguish between numbers and matrices in the way that we write symbols of numbers by lower case letters \((a, b, x, y)\) and matrices by upper case (capital) letters such as\((A, B, X, Y)\).

Subtraction of matrices

For matrices subtraction, the matrices must conform. That is, they both must have the same number of rows and the same number of columns.

The matrices

  und   can be subtracted.

The matrices

  und   can not be subtracted.

To perform matrix subtraction, the corresponding matrix elements are subtracted.

Example

The result of the subtraction is called the difference matrix. The difference matrix has the same number of rows and columns as matrices A and B.
