Here's something that's been coming up a few times in my latest project. Sorry if the answer's obvious, I just can't seem to find an elegant solution to this.

Basically what I'm looking for is an object / method of "keying" out only a certain range of values from a matrix, so that these are output to a smaller matrix containing only the relevant values. This is to be done for float32 data matrices, not video etc. I've currently done it on a cell by cell basis using jit.iter, but finding a MOP will be very nice indeed.

Hi all

Any help is welcome!

float32-value-keying-using-a-mop

its missing the final (and probably the most important) stage of adapting

the matrix to fit the smaller dim. you need wes xray package.

Thanks! just what I was looking for. My humble thanks again also to wes for the great xray objects.

Don't want to be picky, but while we're there- still looking for an elegant solution to the second issue, that of automatically adapting the matrix to as small a dim as possible while getting rid of all unnecessary zeros?

Any ideas?

going to sleep, thanks for the puzzle. jitter needs a zl.

Float32 "Value Keying" using a MOP?
