SpletTo find the rank of a matrix using normal form, we need to first reduce the matrix to its row echelon form or reduced row echelon form. The row echelon form is obtained by performing elementary row operations on the matrix, such as multiplying a row by a non-zero scalar, adding a multiple of one row to another row, or swapping two rows.
