Frequently Asked Questions (FAQ)
What is matrix rank?
The rank of a matrix is the maximum number of linearly independent column vectors in the matrix.
Why is matrix rank important?
The rank is important for determining the solution set of a system of linear equations.
Can the rank be larger than the number of rows or columns?
No, the rank of a matrix will never exceed the lesser of the number of its rows or columns.
What does a rank of zero mean?
A rank of zero means that all elements of the matrix are zero.
How does this calculator find the rank?
It uses row reduction to bring the matrix to echelon form and counts the non-zero rows.
