A Matrix is an arrangement of array of number in rectangular form. Matrices are composed of m rows and n columns. The values inside the rows and columns are referred to as elements. If the rows and columns are equal (m = n), it is an identity matrix. 3x3 is an identity matrix. Here is an online 3x3 matrix multiplication calculator for the multiplying 3x3 matrices. Multiplication of 3x3 identity matrix (nxn), involves multiplication of 3 rows with 3 columns. Enter the values of the matrices into the calculator and find the resultant matrix.
A 3x3 matrix has 3 rows and 3 columns and hence the resultant product matrix which is produced by multiplying two 3x3 matrices is also a 3x3 matrix.
