WebIndeed, a matrix and its reduced row echelon form generally have different column spaces. For example, in the matrix A below: A = 1 2 0 − 1 − 2 − 3 4 5 2 4 0 − 2 F G RREF −−→ 1 0 − 8 − 7 0 1 4 3 0 0 0 0 F G pivotcolumns = basis pivotcolumnsinRREF the pivot columns are the first two columns, so a basis for Col ( A ) is DB 1 − 2 2 C , B 2 − 3 4 CE . WebNow let's put the matrix into reduced row echelon form. Step 1. Get all zeros in the 1st column except for the top term.

WebYou can use the rref (A) function to define the row and null space from the pracma package. The row space will be the cols in which have a leading 1 and null/col space will be the the number of columns less the row space. So code rref (as.matrix (A)) then write a bit to find the pivot columns in your reduced matrix and count your columns.
