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.

Approach

• Create a matrix
• Multiply two matrices
• Verify the result.

Element-wise multiplication using "*" operator:

Syntax: matrix1*matrix*2.....matrix n

Example 1:

This code shows the element-wise multiplication of two matrices data1 and data2, Data comprises 5 rows and 2 columns:

Output:

Example 2:

This code for multiplication of multiple matrices data1,data2,data3. All data comprises 5 rows created using the range operator.

Output:

Example 3:

This code shows the matrix is created using vectors. And matrix multiplication is done.

Output:

Example 4:

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.

Output:
