I would like to make a function such that:
function [] = PullInVars(???????????)
and i want it to pull in all the variables from the main
function... is this possible?  there are 25 or so

Hello Group,
I have a strange problem: the debugger symbols in the Matlab text
editor have become invisible. The "red dot" break point glyph and the
"green arrow" program counter glyph no longer appear in the margin

I have several vector variables that range in size:
<480x1>, <244x1>,<267x1> and so on.  Instead of compileing
all of these variables into one 1 large matrix then saving;
is there a function that can do this without the

Anytime I do something with a figure, i get this error:

   I am wondering if you can set the operating precision
in Matlab.  There is a function called single(var) which
sets the precision for var.  However, is there a way to
set it for all operations in Matlab?  I need to double

Suppose I have an [m,n] matrix. how do i get the (I,j)
index of the first cell in column j with a value > larger
than say x.

I have some problem about mex f90 source code (Compaqe Visual Fortran 6.6)
with Matlab 2007a. My code is contained with 15 modules which are related
each other. For example, I have module  1, 2 ,3 and 4. Mexfunction uses
subroutines in module1, 2 and 3 respectively, and module 3 ...

I am calling a lengthy C++ program(dll) from MATLAB with the
calllib function.  I would like to display a dialog box with
a progress bar that updates as the C++ program executes.
The length of time for the C++ program varies so I never

I am starting to use Fixed-Point Toolbox, within an Embedded
MATLAB Function. I noticed that, since M code does not
support type definitions for variables, the
ProductWordLength attribute in the terms of an equation (its

Solving a system of nonlinear equations
Hi all,
I have an algorithm that outputs 5 nonlinear equations with
x,y and z as unknowns. e.g. aX+bY+cZ=W

i'm the very beginner of MatLab and would like to rise
a one question bevor considering more effort to learn matlab.
It's going about figures witch are in other computer lanquages
being addressed as integer types, like in VB, without a

 I have been struggling to figure out how can I use a
numerical vector as a polynomial function and use it to
implement in quad().
Here is what I tried:

I'm having some major troubles using the low-level HDF5
functions to write character datasets.
My code is as follows:
% String_Dataset.m

This may sound like a rediculous question, but a solution would make
my day a hell of a lot easier.
I have two files, for example we'll call them "F423.dat" and
"F423_spectra.dat"  i have written a program that will import all
