Is there a way to tell Matlab to execute an action for a
number and it's multiples?
For instance:
Every time the number 16 or it's multiples appear (32,48,

I've several plots for which I've done "set(gca,'XScale','log',...)".
This sets the numbers along the x axis to be in standard form, 10^-1,
10^0, 10^1 etc.  I'd rather that they were in decimal form: 0.1, 1, 10.
 How do I do this?

Hello newsgroup,
(I am quite a newbie in MatLab so sorry for stupid questions...)
I want to model a simple gasifier and found that the Control
Systems Toolbox provides a model called GASF based on a 1997

please can anyone help me with this issue
I have array like c
c=[1 2 5 1 9 6 0 4]
by using max (max(c)) function we can find the largest

this is probably simple but I want to replot some lines
(actually tracks) on a map but without having to redraw the
country, lakes, etc outlines each time I plot a new track.  
Do I just assign a handle to each track and then somehow

I need to put a simple constraint and use fminsearch.
min f(x) subject to sum(x)=<1 (or preferably  -1<sum(x)<1)
where x is a vector.
I can use fmincon, but it does not work well for my problem at. Any feedback would be greatly appreciated

I have some functions in which variables are both discrete
and continuous.
The discrete can take 0 / 1 values, and each refers to a
distinct selection.

I want to solve a system of ODE, for example,
x1'=x2-x1^2+x3^2
x2'=-x1*x3-2*x1*x2+x3
for x3, it satisfy, x1^2 + x2^2+x3^2=10;

I have four edit boxes for the user to input for numbers
called "edita", "editb", "editc" and "editd". I am
converting the number into a string using the "num2str"
function so that I can then put it save a file using these

a = [1,2,3,4,5]
b=[1,NaN,3,4,5]
c=[NaN, NaN, 3,4,NaN]
I want to calculate the mean of these vectors without

Is there a way to automatically copy the contents of the clipboard to excel? I'm copying data from another application. I want Matlab to check keyboard input for a Ctrl-C and when it detects it copy the clipboard contents to Excel automatically. How can this be done?

I tried to apply neural nets and as I undestand I have to
follow three steps, create (with any new function), train,
and sim. I have a set of data up to 8000. Do I have to split
those data into two part (for create-train and another one

Hi my Matlab friends,
As a newby in neural nets of Matlab I tried to use the
nprtool that is referred to documentation Neural Network
Toolbox&#8482; 6

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
