How to Transpose a Matrix using Nested Loop
by vsasikalabe Updated: Jan 31, 2023
For every outer loop iteration, the inner loop will run entirely. This enables the repeated processing of several datasets. A loop nested within another loop is referred to as a for a loop.
A transpose of a matrix is a unique matrix where the rows and columns of the original matrix have been swapped. The element at position (i, j) in the original matrix becomes the element at position (j, i) in the transpose matrix. It is represented by a T superscript. For instance, if A is a matrix, then A^T is its transpose.
To transpose a matrix using nested for loops, you would use two nested loops to iterate through the rows and columns of the matrix. The outer loop would iterate through the rows, and the inner loop would iterate through the columns. Other ways to perform matrix transpose are more optimized for specific use cases.
You may have a look at the code given below for knowing more about nested for loop to transpose matrix.
