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
23 Apr 2013	Grid of points within a polygon This function generates an array of points that lie within a given polygon Author: Sulimon Sattari	This submission shows that the author does not understand the potential of built-in inpolygon() function, that can accomplish the same thing with much shorter syntax and faster runtime.

21 May 2013	FFT-based convolution Discrete convolution using FFT method Author: Bruno Luong	Petr	Bruno, sorry, I forgot to mention that I used 2012b. Moreover, speed difference might depend on inputs and I'm lucky with the inputs I use?
16 May 2013	FFT-based convolution Discrete convolution using FFT method Author: Bruno Luong	Luong, Bruno	Petr, I just test with 2012a, the recommendation stands.
15 May 2013	FFT-based convolution Discrete convolution using FFT method Author: Bruno Luong	Petr	Hi Bruno, as for usage recommendations, are they updated for new MATLAB releases? In case of my application for 2D, both nA and nB are greater than 20 (about 200*300 each). However, MATLAB conv2 takes almost the same time as convnfft (even slightly faster).
27 Apr 2013	Min/Max selection Search for k smallest or largest elements in the array Author: Bruno Luong	Rui	Bruno, Sorry. I introduced a typo to your codes. When I replaced // by /, I forgot to add /. Now it is working!

27 Apr 2013	Min/Max selection Search for k smallest or largest elements in the array	Rui	Bruno, Thanks a lot! Now there's a new error on the last line... At first I thought, maybe there's a missing brace, however the I found that was not the case. The new code was working with matlab 32 bit build-in compiler, but not the LCC on linux.

26 Apr 2013	Min/Max selection Search for k smallest or largest elements in the array	Rui	Hi Bruno, I like this function. I got a lot of fun with it on Windows, but when I switched to Linux server with GCC compiler, it did not work. The error was the same as jianbo posted two years ago. I tried to modify minkmex.c file as you suggested, (replace "memset((data+p0), 0, sizeof(double)nz)" with "memset((void)(data+p0), 0, sizeof(double)*nz)") but it did not work. I tired both matlab 2012a and 2010b on our server, but neither worked. Could you help me on it? Thanks in advance! -------------------- minkmex.c: In function ?MinMaxResult?: minkmex.c:293: warning: incompatible implicit declaration of built-in function ?memset? minkmex.c: In function ?LocResult?: minkmex.c:322: warning: incompatible implicit declaration of built-in function ?memset? minkmex.c: In function ?mexFunction?: minkmex.c:544: error: expected expression before ?/? token mex: compile of ' "minkmex.c"' failed. ???
