WebRank of a matrix: Gaussian method. The rank of a matrix is the number of linearly independent rows of that matrix. A row is linearly independent from the other rows when it is not the result of a linear combination of them. So, if we can find a row that is a linear combination of other rows, we will say that this row is linearly dependent. WebRank of the array is the number of singular values of the array that are greater than tol.

WebThen U V' is an mxn matrix of rank r (well, <= r, but I think it's r with high probability). If I just do that and then round to binary / 1-5, though, the rank increases. It's also possible to get a lower-rank approximation to a matrix by doing an SVD and taking the first r singular values. Those values, though, won't lie in the desired set ...
