Unformatted text preview: equations using matrices. i) Matrix Addition Two matrices of the same size may be added or subtracted. Then, A+C is not defined since A is a and C is a matrix! ii) Matrix Multiplication If A and B are two given matrices, then the product AB is only defined if the number of columns of A is equal to the number of rows of B , and the product matrix has the number of rows of A and the number of columns of B . For this reason, AB may not be equal to BA ! Example is not defined. A is a matrix and C is a matrix. The number of columns of A the number of rows of C . iii) Transpose of a Matrix If the rows of a given matrix are interchanged with the columns of the same matrix, the resultant matrix is the transpose of the given matrix....
