NumPy 3D matrix multiplication. Multiplication is the dot product of rows and columns.
How To Multiply Matrices
A 3D matrix is nothing but a collection or a stack of many 2D matrices just like how a 2D matrix is a collectionstack of many 1D vectors.
3x2 matrix times 2x3 matrix. Rows of the 1st matrix with columns of the 2nd. BC is easy enough but multiplying a 2x2 by a 2x3 isnt possible but in the answers my teacher turned it into a 3x2. I recommend you this link which is very instructive.
For each row vector in the 3x3 matrix first loop and each column vector in the 3x2 matrix second loop compute the dot product. Multiplying a 2x3 matrix times a 3x1 matrix yields a 2x1 matrix. The dimension of the matrix resulting from a matrix multiplication is the first dimension of the first matrix by the last dimenson of the second matrix.
A -1 0 2 B -1 0 C -2 1 3 1 4 4 2 1 3 The one in particular that Im stuck on is ABC. 2x3 by 3x2 or QxD by DxW. Multiplication of 3x2 and 2x3 matrices is possible and the result matrix is a 3x3 matrix.
As you can see adding two matrices is the same as adding its elements. The product of two matrices is found by adding the row elements multiplied times. A good way to double check your work if youre multiplying matrices by hand is to confirm your answers with a matrix calculator.
