Hi,
I use some codes with PRTools for dimension reduction. I get a matrix, <3010x60 mapping>.

>> PCA to 71D, 3010 to 71 trained mapping --> affine

But I want it as double. I mean I want to convert this matrix from <3010x60 mapping> to <3010x60 double>. Is it possible?
Regards.

If the mapping is stored in W then by V = getdata(W) a structure is retrieved that stores the mapping. In V.rot the desired matrix is stored.

Thanks Mr. Duin. This is what I look for!
