I am trying to find a way to combine data without using a
loop. My data are similar to the following.
width  = [1 4 4 5 6 10 10 10 16];
weight = [1 1 2 1 1 4  2  2  1];

Dear all, fzero takes too much time to converge so I am trying to change the tolerance. how should I do it?
I tried:
optimset('TolX', [1e-1])
but it doesn't work since when I do

Supposed that I have a list of points (that form a path)
that is dynamically grown (no size known a-priori) during
the running of my algorithm.
In matlab, I can use two solutions to add the next element

I have developed a GUI which implements the Fmincon
functionality. Each optimisation problem would run for
about  5hrs to completely finish and produce results.
I have a requirement werein I need to either STOP, PAUSE,

I've two vectors containing the same strings in different
orders. I want to obtain the index of position of the string
in the second array comparing it with the first array, so I
use this syntax:

I have a lon,lat array, and I would like to locate the index
of those unique locations.  Can I do this easily using UNIQUE?
For example,
tmp = [-18.8605    -159.7955

this might sound stupid or simple....can I do something like
this in matlab?
a= 1, 2, 3 ;
function(a)= [1, 2, 3]

Say I have a 2x3 matrix m and vector v.
m = [1.1,1.7,2.1;...
    3.6,3.3,4.2];
v=[0 1 2 3 4]';

I would like to know whether there is any techniques to show
to image in MATLAB without black portion border? My case is
I tried to superimpose two images with one is the rotate
version of another. So it would be great if the final image

In my program i create an array which looks like:
a = [1;4;65;7;8;4;3;2;5;7;7]
b = [4;7;4;2;23;4;5;7;8;5;4;3]
before i insert them into column matricies i would like to

Hello all.  This is my first post/question so I apologize if
I am not doing things properly but here is my issue:  
Here are the sections of code that I have written.  
1)%circular meshgrid test

If suppose I have this date
'03/28/2008' and i would like to get the last date of the
month (i.e 03/31/2008')
Is there a function in MATLAB that does that?

I have a mesh plot. I want to see it from a different axis point of
view. How do I change the orientation of this mesh plot?
Thanks

Howdy, I've currently got a 2d plot of points (call it a
square) and I want to turn it in to a box by adding a
constant depth to it.
Can anyone help me with this, as I can't seem to crack it

I am using the function xcorr (cross-correlation)as follows:
c = xcorr(x,y,'coeff')
by using 'coeff' it normalizes the sequence so the
autocorrelations at zero lag are identically 1.0.
