Advanced Math Solutions - Matrix Rank Calculator, Matrices

In the last two blog posts, we talked about Row Echelon Form (REF) and Reduced Row Echelon Form (RREF). In this blog post, we will talk about matrix rank. Determining a matrix’s rank will involve using REF or RREF, so make sure to review those blog posts before continuing on.

The rank of matrix is the dimension of the vector space created by its columns or rows. It is important to note that column rank and row rank are the same thing. We will find the rank of the matrix, by using the row rank.

Another way to think of this is that the rank of a matrix is the number of linearly independent rows or columns. Linearly independent means that no rows or columns can be the combination of the other rows or columns.

For example:


Here, Row 2 is a combination of Row 1 and Row 3 (Row 1 + Row 3). Therefore the rows are not linearly independent.

In order to determine the rank of a matrix:
1. Put the matrix in REF or RREF
2. Count the number of non-zero rows 
Let’s see some examples. Please note that I won’t be going over how to put the matrices in REF or RREF.

First example (click here):

1. Put the matrix in REF or RREF
                                                                The matrix is in RREF.
2. Count the number of non-zero rows
                                      There are 3 non-zero rows. The rank of this matrix is 3.

Not so bad! Next example (click here):


1. Put the matrix in REF or RREF
                                                               The matrix is in REF.
2. Count the number of non-zero rows
                                       There are 3 non-zero rows. The rank of this matrix is 3.

Last example (click here):

1. Put the matrix in REF or RREF
                                                              The matrix is in RREF.
2. Count the number of non-zero rows
                                     There are 4 non-zero rows. The rank of this matrix is 4.

As you can see, finding the rank of a matrix is not hard. You just have to make sure you’ve mastered putting matrices in REF and RREF.

Until next time,

  4. I still remember when I was in 7th grade and we had to do all the matrix calculations on rough work and if we committed any mistake in multiplication or Sub/Add values of rows and columns then all our hard work went away into a bunker. But nowadays its just a piece of cake on new scientific calculators and apps. You just need to put value in a matrix format and it gives an accurate answer in seconds with the steps. But some calculations like Word problems are still be doing manually and those students who find it difficult can get help from Professional Essay Writer and then submitted their home work to the teachers.
