Question

what is rank of a matrix

Answer 1

The maximum number of linearly independent vectors in a matrix is equal to the number of non-zero rows in its row echelon matrix. Therefore, to find the rankof a matrix, we simply transform the matrixto its row echelon form and count the number of non-zero rows.

Answer 2

the maximum of linearly independent vectors in a matrix is equal to the number of non zero rows in its row echelon matrix therefore to find the rank of a matrix we simply transformer the matrixto it's row echelon form and count the non zero rows.
