Estimates the number of independent rows or columns of an array.
RANK(a, tol)
a |
- |
An input array. Defaults to the current series. |
tol |
- |
Optional Real. Singular value tolerance. Defaults to: |
An integer, the estimated rank.
W1: rand(3)
W2: ravel(W1, W1)
W3: rand(6)
rank(w1) returns 3.
rank(w2) returns 6.
rank(w3) returns 3.
RANK use SVD to compute the singular values of an array.
