Using this library, we can perform complex matrix operations like multiplication, dot product, multiplicative inverse, etc. In this post, we will be learning about different types of matrix multiplication in the numpy library.
In order to find the element-wise product of two given arrays, we can use the following function. The dot product of any two given matrices is basically their matrix product. The only difference is that in dot product we can have scalar values as well. Numpy offers a wide range of functions for performing matrix multiplication.
If you wish to perform element-wise matrix multiplication, then use np. The dimensions of the input matrices should be the same.
