Find basis for row space

WebI have the row space as r o w ( A) = s p a n { ( 1, − 1, 3, 0, − 2), ( 2, 1, 1, − 2, 0), ( − 1, − 5, 7, 4, − 6) } I know that finding a basis for this set is what is needed then simply counting the number of vectors in the set will give me the answer but I don't know how to proceed. thanks. matrices vector-spaces Share Cite Follow 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.
