Returns the indices of the columns to remove to construct a full rank matrix

findRedundantCols(m, TOL = 1e-09)

Arguments

m

Rank-deficient M by N space matrix where M >= N in dgCMatrix format.

TOL

tolerance for column matching

Value

Indices of columns to remove from m so that the remaining matrix is full rank.

Details

Given a rank-deficient M by N sparse matrix, where M >= N, in dgCMatrix format, returns the indices of columns to remove from the original matrix so that the resulting matrix is full rank.
