How could I have a variable's value show up automatically in
an edit box? For some reason I can only show strings in the
edit box and the inspector does not let me a variables value.
Thank you!

is there a way to export matlab code to latex? i'm thinking of a 'big'
matrix for example.
TIA,

hi friends,
please, i need code for isolate object from background.
thanks

I got a problem. My problem is to write a code which checks  4th column element of a matrix by scanning each row and if the element is found to be some number, say 10, remove the whole row from the matrix and copy it into a new matrix. So the new matrix should have all the rows ...

I'm new to Matlab and this is my first post, so bare with me :).
Basically, I'm using structures, and I was wondering if
there are specific commands for "setting" a current
structure, so that all variables created or accessed

I have written some code which calculates an EWMA estimate for the
correlation matrix of two time series. Suppose that X and Y are our
time series vectors of length N (say N daily observations of two
market interest rates) with X_1 the oldest observation and X_N the

I work as a system design engineer and now and then I am
faced with measurement values that are not exact, but have a
tolerance attached to them. Since I work with algorithms and
larger systems I often need to process and combine these

I was wondering if someone has found a quick solution to
this problem:

I've run into a strange problem when trying to use a color
gradient in the z-axis of a 3-D bar plot. I want to get the
bar3 to produce a plot like this:

The Matlab function "quadprog" may find a local optimum for the
convex, but not strictly convex quadratic programming problem. Is
there any function/method to find the global optimum of a QP with
positive semidefinite objective matrix H?

Hi, i need to model a tank draining under gravity in a
simulink model.  i am unexperienced with implementing a
nonlinear equation in simulink.  would it be easier to model
this system with an s-function or embedded matlab function?

I would like to know the sampling rate of digital input
block in SIMULINK. Also can we change sampling rate?. I want
to pass an external clock of 104 KHz to my simulation
through parallel port.

I have 2 questions.
first.
I am producing a lot of plots and saving them to look at
later. Is there any way to create a plot with
