I have this data sample and plot it in Matlab. The data is collected
from some medical experiment of mice. In the previous analyzes, we
select the threshold manually(not very accurate). Now we are trying to
program to automatically select the threshold by computer, which will

I have a mixed wav file is consist of different voices. For
example, a person is speaking and at the same time, there is
playing a song on the background of speaker. I want to split

I have two arrays (2D) and would like to copy some values from array2
to array1. The exact index location in both arrays are known. Can it
be done without using a for loop? Here is the simple version of the
code that I am using. Just need to do it without a for loop. Any help

I have a series of plots appearing in the figure window in
succession, after pre-determined intervals (decided by the
'pause' command).
Accompanying these plots, are sounds played aysnchronously

okay, so i don't know if this is new or if i've just been
working to long, but, i'm using R2006a V7.20 and it appears
that MatLab's default choice for normalizing the eigen
vectors of the general eigen value problem is to normalize

I have a CT scan of an image of bone.  I want to analyze the
outline of the bone.  I've tried to use bwtraceboundary and
imfill and both work.  
The problem is that due to quality issues the bone images in

I have an array of string values:
x=['test1' 'test2' 'test3']
When I refrence x(1) I get back a value of t. How do I get
MATLAB to return 'test1' when I type x(1)?

I would like ask if there is a function in matlab that can solve the
following equation about x:
-x^5 +20*x^3 +60*(2*t+1)*x -60*p=0
where t is declared as syms and p is a constant. Can i solve it for x?

Hey everyone:
I've got this funky binary data file that has a multitude of
data types in it.  I've managed to parse out the bytes by
field and data type, leaving me with arrays of 8-bit bytes

i can sucessfully connect to the serial port and recieve
data from the marcator digital indicator i am using.  I
want to idiot proof my program for whoever uses it so... is
there a way to see if the indicator is connected? i tried

I'm making a MATLAB code that calculates the 2-D trajectory
of a point-mass body. However, unlike the examples for of
this type in textbooks I'm also including a real atmosphere
model and drag coefficient data as a function of Mach

I recently inherited some code that was written as a script.
I prefer to work with functions and so was doing some minor
rewrites, but I'm running into a problem with some of the
variables.  Specifically, Matlab treats one of them as a
