Re: masked arrays and nd_image: msg#00020

python.numeric.general

Subject: Re: masked arrays and nd_image

I did not write nd_image with masked arrays in mind, I imagine it won't work for most functions. I am not planning to support masked arrays

. If you just want to mask out some of the results, apply the mask afterwards. If you actually want to deal with masked values in the convolution itself, you are out of luck with the convolve1d function, it does not support that. In that case you could try to write your own, using the generic filter functions (see the manual).

Cheers, Peter

Hi all.

I just tried to use a masked array with nd_image, namely to pass it to the convolve1d() function, and I got:

error: getShape: couldn't get sequence length.

Does someone know if it possible at all to use nd_image on masked arrays? Or if there is a possibility to do operations on masked images without using the ma module?

thanks. curzio
