how to find the Estimating Model Parameters??
You need to better explain what you are trying to do exactly. Arkadiy "Mohd Firdaus " <mfirdausrahim86(a)yahoo.com> wrote in message <hqr7f4$1l2$1(a)fred.mathworks.com>... hello, i am firdaus. i cannot find the Estimating Model Parameters.. juz only in the example but it cannot work. ... 23 Apr 2010 20:55

Problem with engwindemo.c - "unresolved external symbol"
I am trying to get into the MATLAB API for C/C++, therefore I wanted to test compile "engwindemo.c" in the Command Window using "mcc -m engwindemo.c" or in Visual Studio 2005. Either way I get the following error message during linking: 1>engwindemo.obj : error LNK2019: unresolved external symbol "_mxDestroyArray" ... 26 Apr 2010 06:57

Saving 'Visible','off' figures
Hi everybody, I'm generating a bunch of figures from my simulations: I first tried the command: figure('Visible','off') plot(x,y) saveas(gca,'name.fig') everything worked fine, except that when I open the figure in Matlab with open('name.fig') it is opened in invisible mode. I'd like to avoid this because I... 29 Apr 2010 13:31

how to cluster points into n-unknown groups?
If i have a n unknown points and n unknown clusters, is there any algorithm which will try to group the points into the most appropriate groups. I could use K-Means clustering algorithm but with that you have to give the predicted number of groups. For my problem, I do not know how many groups there will be - it ch... 25 Apr 2010 15:34

Reading of Simulink block output value
In Simulink, I would like to read output of a block during execution of the simulation. For a 'Gain' block at top level (model xpcosc.mdl), I can read/write block parameter value: set_param([gcs '/Gain'],'Gain', '100^2 *5') get_param([gcs '/Gain'],'Gain') This works in external mode too. Does exist an equivalen... 23 Apr 2010 20:54

Wavelet toolbox and linear system
Hi, I would like to use the wavelet toolbox to speed-up the solution of sparse linear systems. The idea is the following: given a linear system Ax=b, decompose A and b in a Wavelet space, solve the linear system in this space and recompose the solution of the linear system. My code works for a 1 level decomposition,... 29 Apr 2010 04:34

find roots of a spline
Hi, I'd like to speed up my code for the following problem: input: two vectors x, y (numel(x) = numel(y) = ~5e5) output: roots of the cubic spline through (x,y) I've written a function 'rootspline' to get the roots of the piecewise polynomial form of the cubic spline 'pp' (see below), so I run pp = spli... 23 Apr 2010 20:55

Normal direction of faceNormals
Hi, Just wondering if there is anyone out there with specific knowledge of the TriRep faceNormals class, as I have a couple of questions. I'm using a triangulated surface, and looking to find the direction of the normals. However, it's important that the normals are in a consistent direction, i.e. all pointing ou... 23 Apr 2010 20:55

relative error question
can u pls solve this? i tried all what i know. the elationship between the resistance R of the thermistor and the temperature is given by (1/T)-1.129241*10^(-3)=2.341077*10^(-4)*log(R)+8.775468*10^(-8)*(log(R))^(3) where T is in Kelvin and R is in ohms. A thermistor error of no more than 0.01C is acceptable. T... 24 Apr 2010 09:24
