23 Dec 2009	Despiking This function remove spike noise from data. Author: Nobuhito Mori	P.S. I just noticed that this works only if x is a vector. If x is an array, the "official" nanmean will calculate the mean columnwise or along a specified dimension. What they do there is to set the NaNs to zero, sum up the columns and divide by the number of no-NaNs: function m = nanmean (x,dim) if nargin<2, dim=1; end nans = isnan(x); x(nans) = 0; sumx = sum(x,dim); m = sumx./sum(~nans); Save the file as nanmin.m in a directory on the Matlab path. hope this helps, GS
23 Dec 2009	Despiking This function remove spike noise from data. Author: Nobuhito Mori	Jac Billington write your own nanmean function, e.g.: function m = nanmean (x) x = x(~isnan(x)) m = mean(x)

25 Nov 2009	TCP/UDP/IP Toolbox 2.0.6 TCP/IP connections or UDP packets in MATLAB Author: Peter Rydesäter	I did not manage to compile the c-file pnet.c. I am running Matlab 2009a on a Linux machine with a 2.6.27 kernel and a 4.3.2. gcc compiler. Can anyone help me? P.S. I recieve the following error messages: >> mex -O pnet.c Warning: You are using gcc version "4.3.2". The earliest gcc version supported with mex is "4.1". The latest version tested for use with mex is "4.2". To download a different version of gcc, visit http://gcc.gnu.org pnet.c:104: error: expected identifier or ‘(’ before ‘/’ token pnet.c:170: error: expected identifier or ‘(’ before ‘/’ token pnet.c: In function ‘newbuffsize’: [... many more error messages...] pnet.c:1158: error: expected expression before ‘/’ token pnet.c:1174: error: expected expression before ‘/’ token mex: compile of ' "pnet.c"' failed.

13 Mar 2010	TCP/UDP/IP Toolbox 2.0.6 TCP/IP connections or UDP packets in MATLAB	anon donor	I was able to achieve >512mbps (that's 0.5 gigabit/sec) of read or write by modifying pnet.c as follows, and recompiling the mex extention: ---- edit of pnet.c start here---------------- int tcp_connect(const char hostname,const int port) { + int optval; + int result=0; if(ipv4_lookup(hostname,port)==-1) return -1; con[con_index].fid=socket(AF_INET, SOCK_STREAM, 0); + optval=1; + result = setsockopt(con[con_index].fid, +IPPROTO_TCP,TCP_NODELAY,(char ) &optval,sizeof(optval)); + optval = 5121024; + result = setsockopt(con[con_index].fid, SOL_SOCKET,SO_SNDBUF,(char ) &optval,sizeof(optval)); + result = setsockopt(con[con_index].fid, SOL_SOCKET,SO_RCVBUF,(char *) &optval,sizeof(optval)); ---- edit of pnet.c ends here---------------- with the modified pnet, executing pnet read/write calls using a buffer of 512kbytes gave very high throughput. Thank you very much peter , for contributing this and sharing the source, it's been very useful.	Comment only
06 Mar 2010	TCP/UDP/IP Toolbox 2.0.6 TCP/IP connections or UDP packets in MATLAB	Igory iBass	If anybody had such wrong like a 'pnet_sendvar bla bla bla', correct youself pnet_putvar M-file. - Write "pnet_putvar" instead of "pnet_sendvar" on LINE 46. Enjoy;)	Comment only
18 Feb 2010	TCP/UDP/IP Toolbox 2.0.6 TCP/IP connections or UDP packets in MATLAB	Colin Selleck	Anyone have luck running this under MAC OS 10.6.2 Snow Leopard? It seems to put MATLAB in an infinite busy state.	Comment only
28 Jan 2010	TCP/UDP/IP Toolbox 2.0.6 TCP/IP connections or UDP packets in MATLAB	Christopher Volpe	When the latest version loads,the console output claims that it is version 2.0.5, as that's the version that's hard-coded into pnet.c. Is this merely a cosmetic error?	Comment only
