Introduction to Matrix Rank Calculator

The rank matrix calculator is an online free tool useful for calculating the rank of a matrix of order 2, 3 or 4. It calculates the number of nonzero rows or columns left after reducing the matrix into echelon form.

In matrix algebra, the rank of a matrix is used to know whether the system is controllable or observable. We usually use the rank of a matrix to find the number of nonzero rows or columns. Finding the rank of a matrix by hand is not easy. So we introduce a tool online that can easily compute a matrix's rank.

The Formula used by Rank of Matrix Calculator

The rank of a matrix is the number of nonzero rows or columns. It is used to check whether the matrix is singular or nonsingular. The rank calculator uses echelon form by applying row and column operations on the matrix.

The rank of a matrix can find out by using the following steps:

  1. To make the echelon form of the matrix, convert the numbers to zero below the diagonal elements.
  2. To make zeros, we can use column or row operations.
  3. After transforming into zeros, the number of remaining nonzero rows is the rank of the matrix.

You can also check that the given matrix is singular or nonsingular if:

  • If the order of the matrix is equal to the rank, then the matrix will be nonsingular.
  • If the order of the matrix is greater than the rank, the matrix will be singular.

How to Calculate Matrix Rank with Calculator?

You can compute the rank of a matrix by following these steps:

  1. In the first step, you need to enter the number of rows and columns of the matrix in their respective boxes.
  2. Now enter the value of all entries of the matrix. Or you can use the random button to select a random matrix.
  3. Click on the calculate button.

You will get the result a few seconds after clicking on the calculate button of this matrix rank calculator.

Why use a Calculator to Find Matrix Rank?

The concept of rank is important in matrix algebra because it checks whether the matrix is singular or nonsingular. It is also used to find the system of linear equations that is controllable or observable. But when you are doing manual calculations, sometimes you don’t know what operation should be applied. You can get stuck on it. We provide you with a free tool that can help you find the rank of a matrix without doing any manual calculations because this tool offers you a step-by-step solution where every row of column operation is explained.

Benefits to Calculate Matrix Rank with Complex Numbers

Since the matrices are used to solve the system of linear equations and find out their solutions, the rank of the matrix is also important. It tells whether the system has single or multiple answers. The rank calculator can help you in many ways, such as:

  1. Rank of matrix calculator can save your time from manual calculations.
  2. It gives a step-by-step solution to calculate the rank of 4x4 matrix. So that you can understand every step performed.
  3. Using this tool, you can never get stuck in the column or row operations while calculating the rank of the 3x3 matrix.
  4. It is a free online tool that provides many features to improve your learning skills to calculate the rank of the 2x2 matrix.
  5. It is reliable because there is no chance of error in its calculations.
  6. Matrix rank calculator can handle up to order 4-by-4 matrices easily.
