By multiplying the first row of matrix b by each column of matrix a, we get to row 1 of resultant matrix ba. Ask question asked 8 months ago. If they are not compatible, leave the multiplication.
For Example, If You Want To Multiply 3 Matrices Called A, B And C In That Order, We Can Use Np.dot(Np.dot(A, B), C).
Say we’re given two matrices a and b, where. However, if we reverse the order, they can be multiplied. Take the first matrix’s 1st row and multiply the values with the second matrix’s 1st column.
To Check That The Product Makes Sense, Simply Check If The Two Numbers On.
By multiplying the first row of matrix a by each column of matrix b, we get to row 1 of resultant matrix ab. Now you can proceed to take the dot product of every row of the first matrix with every column of the second.

The Matrix Behind The Scenes What Is A Matrix?
To understand the general pattern of multiplying two matrices, think “rows hit columns and fill up rows”. The dimensions of a, b and c should be matched accordingly. Here in this picture, a [0, 0] is multiplying.
[1] These Matrices Can Be Multiplied Because The First Matrix, Matrix A, Has 3 Columns, While The Second Matrix, Matrix B, Has 3 Rows.
Even so, it is very beautiful and interesting. You can only multiply matrices if the number of columns of the first matrix is equal to the number of rows in the second matrix. For example, the following multiplication cannot be performed because the first matrix has 3 columns and the second matrix has 2 rows:
