The multiplication process of matrices is a little bit difficult compared to the addition process. Do you know how to take the dot product of two vectors? Similarly, for the second multiplication, type the following formula to multiply the matrices in excel:

Matrix multiplication can only occur if the two matrices conform, that is given two matrices a and b, the operation ab (axb) can only occur if the number of rows of b match the number of columns of a. So if a is a mx2 matrix, for ab to exist, b must be some 2xn matrix.

For example, m1, m2, and m3, then as per your requirements, first multiply two of the matrices and then multiply the product with the third matrix. To perform multiplication of two matrices, we should make sure that the number of columns in the 1st matrix is equal to the rows in the 2nd matrix.therefore, the resulting matrix product will have a number of rows of the 1st matrix and a number of columns.

The thing you have to remember in multiplying matrices is that: For example if, matrix a has 2 rows and 3 columns (a:

If So, Think Of Each Row Of The Left Matrix And Each Column Of The Right Matrix As A Vector.

Therefore, we first multiply the first row by the first column. Then we will check if the matrix can be multiplied or not by checking that the column of the first matrix should be equal to the row of the second matrix. Similarly, for the second multiplication, type the following formula to multiply the matrices in excel:

The Number Of Columns Of The First Matrix Must Be Equal To The Number Of Rows Of The Second To Be Able To Multiply Them.

Solve the following 2×2 matrix multiplication: Basically, you can always multiply two different (sized) matrices as long as the above condition is respected. The following process will help you to know how to multiply two matrices.

Make Sure That The The Number Of Columns In The 1 St One Equals The Number Of Rows In The 2 Nd One.

Do you know how to take the dot product of two vectors? For solving this problem, we will first input the two matrices from the user. If you need mathematical matrix multiplication (dot product), use numpy.dot (see examples behind the link).
