I have created a Simulink model to test a Kalman filter
that I designed and to replicate real data input, I am
using an embedded Matlab file that calls a function within
this file called "myWait". I placed this function at the

Everyone that have this code, may you send me because i needed for my thesis.

I'm trying to do some autocorrelation calculations and I'm
using the Durbin-Watson statistic. I call dwtest and I get
an error messsage:
??? Undefined command/function 'pvaluedw'.

I am trying to run a cluster analysis on a similarity
matrix which I calculate using a different similarity
coefficient than is available in the pdist function
(Gower's similarity coefficient). I know the similarity

Dear Helper,
I am trying to implement the bisection method (BM) on a
specific function. As you know to do the BM we need to set
the function f(x)=0, find an initial guess of the interval

I have a MATLAB Distributed Computing Toolbox (DCT) question. It's about
the "distributed arrays" functionality of DCT. I'd appreciate any help.
Here is a code segment. It is part of a .m file and this .m file runs and
completes successfully, in other words there aren't problems ...

I am sorry for asking such a basic question. I have searched the internet and tried several different versions, but I still cannot get it to work.
Why when I run this code:
----------
fwrite(txtFile,'\n');

Hi
excuse my ignorance, I have a set of 80 jpegs which i have
written a script for that measures a parameter I'm
interested in. Where should I start learning about batch

I have a question concerning colormaps.
I want to draw on a black and white image a green perimeter.
To do so, I thought I would take the black and white image
(each pixel being mapped for a gray(256) colormap), change

I have an image that has multiple triangular regions, and I
know the coordinates of vertices to those triangles with the
help of delaunay function.
How can I extract all the pixels located inside those

I try to demonstrate the aliasing effect on wav files, is
this correct? I don't know how aliasing sounds like...
[data,fs,nBits]=wavread('filename.wav');
gr=size(data);

I want to an array that is inside a cell array empty
let us say we have a, which is a cell array , I want to make
the array in the postion a(3,3) empty ((this means contains
nothing, so that when apply the function isempty the answer

Is there some function in matlab that plots the basis function only for a
B-spline and not the B-spline itself?

I have some data like

  I am looking for a structured quadrilateral mesh
generator for polygon domains (preferably arbitrary
domains). Most codes always use triangles. Is there a way to
merge the triangles into quadrilaterals? Please help me.
