Elementwise Matrix Multiplication in R
In a matrix, as we know rows are the ones that run horizontally and columns are the ones that run vertically. In this article, we are going to perform element-wise matrix multiplication in R programming.
- Create a matrix
- Multiply two matrices
- Verify the result.
Element-wise multiplication using “*” operator:
Syntax: matrix1*matrix*2…..matrix n
This code shows the element-wise multiplication of two matrices data1 and data2, Data comprises 5 rows and 2 columns:
This code for multiplication of multiple matrices data1,data2,data3. All data comprises 5 rows created using the range operator.
This code shows the matrix is created using vectors. And matrix multiplication is done.
An example that shows multiplication column arrangement and matrices data1 and data2 and multiplied. Column wise we are going to perform matrix multiplication data1 and data2 comprises 3 columns and elements are created using vector.
