matrix_rank {ramify} | R Documentation |
Compute the rank of a matrix using the singular value decomposition (SVD) method.
matrix_rank(x, tol)
## Default S3 method:
matrix_rank(x, tol)
## S3 method for class 'matrix'
matrix_rank(x, tol)
## S3 method for class 'data.frame'
matrix_rank(x, tol)
x |
an object that inherits from class |
tol |
Threshold below which SVD values are considered zero. |
The singular value decomposition method simply computes the SVD of x
and returns the number of singular values of x
that are greater than
tol
. See the function rankMatrix
in package
Matrix
for alternative methods.
