I'm trying to read some data from workspace into Simulink, using the
From Workspace block. The data is a 1D array and i have to pass some
time data as well, according to MATLAB.
The problem is that i can't acces my data, because it's embedded into

I am using menu & inputdlg to specify some inputs or to
choose from multiple choices, can I combine them to appear
in one window and in this window , I can choose from given
choices and in the same window I enter a specific value that

There's been a long time since I didn't use matlab and
I've forgotten which function to use if I want to plot an
image with followong properties :
C is a 1 by 100 vector containing intensity

I need to calculate polylogarithm functions (given by
infinite series) in MATLAB, but I can?t find them. Is
there a code available somewhere? Mathematica has a code
for it - can I import it to MATLAB?

Hi
I am building a pattern which is a few feet x few feet in
dimension. I can create a large image but ofcourse, when i
try to save the large image through matlab i have memory

Hi,
I know that i can change the background color of a plot using the command 'whitebg'. Is there a way that I can use this command, or any other option, to color the plot in different colors, like : the y-axis 0-3 will be 'blue' , the y-axis 3-7 will be 'green' , and so on ?

I have 2 sets of variables:
x={'test1';'test1'}
y=10
and

       i am new to Matlab programming, however I have used
C in the past. I am trying to use a loop which loops 10
times in total and every time I want it sum a number up. I
need to clarify what I mean as I am not very good at

I must set some tif tags like TileWidth that are listed by
imfinfo and unfortunately add two new ones which are not
listed by imfinfo called "Position: <number>" and "Subfile
Type: <string>"

i would like to analyze my data with linked plots and the
brushing tool (R2008a).
The variables and the plots are calculated/created in a
separate function. So after the run of the function i have

I'm trying to use calllib to access an external function in
a dll. I can successfully load the dll and libfunctions
gives the function definition as:
[lib.pointer, voidPtr] functionname(uint32, uint32, voidPtr)

how could i speed up my simulink

Maybe stupid question but I'm new user of matlab. I've got
AVI video that consists of 258 frames and I need to extract
all frames into 258 bitmaps. Can you help me please?
Thank you.

while using matlabs new object orientated features (7.6.0.324, using
ubuntu 8.04), I come across a strange behavior quite often. I am
editing my classdef m files in the matlab editor, save them, and then
execute a init.m file, that does all sort of things, and also

i would like to solve the basic parabolic heat equation
over two joined rectangular regions but with different
values of 'd' in each ('d' being the heat diffusion
coefficient).
