30 Jun 2013 N-dimensional histogram Compute n-dimensional histogram Author: Bruno Luong

To Dave, see my comment in May 2009. This is how it supposes to work.

24 May 2013 CStr2String Fast concatenation of cell strings to a string as C-Mex Author: Jan Simon

MATLAB cell concatenation is extremely slow. Jan's FEX is a must for those who care about speed.

16 May 2013 FFT-based convolution Discrete convolution using FFT method Author: Bruno Luong

Petr, I just test with 2012a, the recommendation stands.

26 Apr 2013 Min/Max selection Search for k smallest or largest elements in the array Author: Bruno Luong

Rui,
The error is in line #544 (look at the error message). Try to replace the C++ comment style
// in case the positive set is unordered
by C comment style
/* in case the positive set is unordered */

23 Apr 2013 Range intersection Mathematical intersection of range composed of a union of intervals Author: Xavier Xavier

Good coding, fast

29 Jul 2013 N-dimensional histogram Compute n-dimensional histogram Author: Bruno Luong arnold

hist3 also gives the counts with flipped dimensions... strange

29 Jul 2013 N-dimensional histogram Compute n-dimensional histogram Author: Bruno Luong arnold

very nice work, but I see the same problem as J. Dimensions seem to be switched. Some non random data I have. Doing a scatterplot clearly indicates the highest data density in the upper left, using histcn clearly gives the same distribution, yet the highest counts are in the lower right. Yes, set everything to axis xy.

It must be something simple, a hint please :)

13 Jul 2013 kronecker Kronecker tensor product Author: Bruno Luong Altman, Yair

Congratulating in having your efficient code incorporated in the stock KRON function in R2013b - well done, Bruno!

25 Jun 2013 N-dimensional histogram Compute n-dimensional histogram Author: Bruno Luong DaveD

This is a very useful piece of code, but it returns extra dimensions if any of your points fall along an outer edge.
