## Description

• This function calculates the subtraction of the two matrices.
• In , and are any two matrices.
• Minus is one of the four basic operations of arithmetic.
• Minus operation is the opposite operation of Add.
• Matrix minus is the basic operation of subtracting two matrices with the corresponding entries.
• Two matrices must have an equal number of rows and columns.
• The minus of matrices A and B is denoted by • Suppose the number of rows in the first matrix is more than the second matrix,this function will return the extra row entries with the same number.
• Suppose the number of rows in the second matrix is more than the first matrix ,the extra row values of the second matrix will be ignored.
