How to Find the Rank of a Matrix (with echelon form) | Linear Algebra

The rank of a matrix is the number of linearly independent rows or the number of linearly independent columns the matrix has. These definitions are equivalent. To find this number, we can reduce a matrix to row echelon form and count the nonzero rows, whose leading entries are called pivot numbers. We'll solve five rank of a matrix examples in this lesson. #linearalgebra
