Given n by n similarity this function first calculate the Laplacian
1 | produceU(similarity, ncol, type = 2, all.eig = FALSE)
|
similarity |
an n by n matrix |
ncol |
number of columns of the output matrix U |
type |
The algrithm that should be choosen. options are 1, 2, and 3 |
all.eig |
a logical value indicating whether all the eigenvector should be compute or not |
n by ncol numeric matrix that contains the ncol tops eigenvectors of Laplacian matrix as column
