lsqlin vs lsqnonneg
lsqnonneg works fine and returns resnorm of 9 10^-8 while lsqlin returns peaky solution and the resnorm of 1.12 10^-5. The returned solution in this case is ok, not as good as in the case of lsqnonneg. Since the problem is large scale, I am under impression that I can not use lsqnonneg. I would like to use lsqlin... 26 May 2010 12:27

How to generate an isosurface with a nonuniform mesh (with variable mesh density) ?
I have the same frustration using Isosurface. It looks like all Matlab 3D visualization tools were not designed for real work, but for fun only. In real world, nobody uses the 50x100x50 volume set as the examples do. Usually it is at least 256x256x256. The isosurface also doesn't take uint8 or uint16 data, which ar... 17 Jun 2010 02:27

How to make isosurface() work with uint8 data
isosurface is used to create surface from a volume. For example, an MRI dataset could be 512x512x400. This is 104 MB in uint8. However, the isosurface can only take double, which is 838MB memory space, which immediately overflows. Even if downsample the dataset to 256x256x200, that's still a very large dataset if... 17 Jun 2010 01:23

ARBITRARY BIN LOCATION FFT
Is it possible to specify arbitrary bin locations using the FFT function? So, I don't want the bin locations to be determined by by sampling rate and number of FFT bins, but instead I want to be able to specify specific bin locations that aren't evenly or regularly spaced. Thanks, Rene Allard. ... 2 Jun 2010 08:43

Angle Recovery in Fourier Mellin Image Registration
