I am relatively new to Matlab and am encountering a problem
i wish to estimate the parameters for for lognormal
distribution , student-t and GPD using  monthly logreturns.
I have attempted to use MLE with "lognfit" but am having

Hi,
I’m using the nlinfit function. The following code works
fine:
[betahat, r, J]=nlinfit(x, y, 'MyFunction', beta);

I've found very strange behavior of mex32:

32.000000  - wrong result this is not =log(1.1)

Hello All -
I have created a couple of edit text boxes in my gui via
the guide, and I am curious how you would be to change the
values in the text box after a user has input one already.  

Hello. I am having a problem opening a serial port. I'm
using the simple code:
s = serial('COM1');
set(s, 'BaudRate', 4800);

i am trying to plot the power spectrum(life was better before hearing
that word!) of a road profile according to ISO 8608. the road profile
signal is 100 meters long with a resolution of 0.01m.having the power
spectrum (welch method), i would like to plot it on a logscale.

This is the strangest thing I've ever seen!  The computation of a mathematical expression is not giving what it obviously should!  From the command line:

K>> comps

I am trying to generate a list of 36 random numbers. I am
using:
RandomNumber=randperm(36);
However, my problem is that I generate the exact same

I have a program that I am attempting to call from the shell
with a script.  I plan to use cronjobs to run it every hour
or so... however, my matlab program (FTSWeatherPlotWrapper)
not only pops up a matlab command window, but it also

I cannot remember the name of the function that allows you
to merge 2 arrays and only keep the elements not in common
(or in common). I am getting lost in the help!
Thank you for your help!

Is there any way I can include a requester on a GUIDE
created GUI?  I am trying to have multiple input options
that have default values along side with several radio and
push buttons.

I have a poorly triangulated 3D mesh of not simple objects.
The meshes are represented as a matrix of vertices and a
separate matrix for how to connect these vertices  into
faces. In the mesh there are various  spurious (0 area)

My application has GUI whose display dimensions exceed the
window size of my PC. I have tried changing the dimensions
using property editor but it doesn't seem to accept what I
put in. How can I change the GUI dimensions to make it fit

To a certain extent, subfunctions are accessible from
outside the workspace of the mfile in which they reside.
For example, if I do the following in the base workspace,

I'd like to assign a variable to the memmapfile structure
so that I can write back to the file without having to use
the structure variable.  For ex:
m = memmapfile( ... )
