myorth(X) makes an orthonormal basis for the space spanned by the
X. The number of columns returned equals
which is the rank of
myorth(X, tol_ = 1e-09)
tuning parameter for the rank.
The calculations are based on the singular value decomposition
myrank(X) is the number of singular values
X that are larger than
myorth returns a matrix, whose columns form an orthonormal
myrank returns a single number, which is the rank of
In the special case where
X has a single column,
c is a positive constant.
