Help fitting transcendental exponential relationship to experimental data
I am trying to fit diode data to a model that contains all four components of current conduction across a diode, namely: Thermionic emission, Tunneling, generation-recombination, and leakage. (if you are a very interested reader please see: doi:10.1016/0038-1101(91)90031-S) There are several papers that successful u... 14 Jul 2010 18:43

checkboxes in word documents
Hello, I need to check and uncheck check box form field objects in a word document. I got this far: docFilename = 'TEST check box form.doc'; hdlActiveX = actxserver('Word.Application'); hdlActiveX.Visible = true; trace(hdlActiveX.Visible); hdlWordDoc = invoke(hdlActiveX.Documents, 'Open', docFilename); h=... 15 Jul 2010 16:30

Nelder-mead Algorithm, Doubt on number of Parameters
Hi, I am trying to implement nelder mead algorithm to an optimization problem usng derivative free approach. But the problem is I have a large number of parameters (around ten thousand). So to use this I have to to create a simplex of "number of parameters + 1" sides and evaluate function value at each point. This i... 15 Jul 2010 13:10

Color Order Issue
Okay, I'm plotting data in a GUI on an AXES which is on a PANEL. 1) I plot the data to the axes handle (This works fine) 2) generate a new axes to overlay on top of the first axes and plot some more data When generating the second axes, I *think* i set the COLORORDER property for it by writing: set(data_... 15 Jul 2010 04:28

Compiling C code in matlab
Hi, I am trying to compile a c code in matlab. The functions name is qp.c which calls another function pr_logo.c. I've added libraries like stdafx.h and targetvar.h along with mex.h in the current directory, that being C:\...\Matlab\R2009b\extern\examples\mex. I've used mex -setup and mex qp.c pr_logo.c to compile t... 20 Jul 2010 03:45

spherical cap harmonic analysis
Hi, I'm just wondering if anyone is aware of a Matlab code that does spherical cap harmonic analysis. I would be using it to calculate the magnetic field due to a magnetized crustal region. Thanks, Reka ... 14 Jul 2010 17:37

stmcb with coefficient constraints
I would like to use stmcb to design IIR filters that approximate a measured impulse response, but in addition I would like to add some constraints such that the poles and zeroes of the designed filter are restricted to certain regions. Is there a way to do this? Is the stmcb source code published anywhere so that I cou... 14 Jul 2010 16:31

Better quality graphics in PUBLISH output
Hi, I am working on a MATLAB program that needs to produce a nice-looking report. The PUBLISH command is very nearly perfect, except the quality of the graphics that end up in the report are not very impressive. They look terrible when printed. I can manually export a figure to a PDF file and it prints out be... 9 Aug 2010 15:40
