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. WebJul 1, 2024 · Method for Finding the Basis of the Row Space Regarding a basis for R a ( A T) we recall that the rows of A r e d, the row reduced form of the matrix A, are merely …
http://www.gregthatcher.com/Mathematics/RowSpaceCalculator.aspx WebAs for finding a “nice” basis for the column space, that really depends on what “nice” means. That said, I find that the basis that you get by taking the columns that correspond to pivot columns in the rref doesn’t usually produce a “useful” basis.
