I need to estimate parameters of a defined structure of a
transfer function. Suppose for example the transfer
function K/(s+a).
Given frequency data (module, phase and frequency for each

Contour and contourf appear to produce slightly different
contour boundaries next to NaN 'holes'. The ones drawn by
contour terminate short of those drawn by contourf. This
wouldn't be a particularly noticeable problems were it not

I have a simulink model and i want to implement an s-
function to model the changing area of two overlapping
circles.  i would like the user to specify the radius of
the circles from a GUI.  what do i need to code in my GUI m-

Hi everyone;
I'm working on vectorizing code and I'm stumped by a structure.
Here's the original scenario:
function [sub_lat,sub_long,sub_dataU,sub_dataV] =

I have a series of Matlab GUIs with different
functionalities (database, visualisation, excel data
transfer). All of these compile straightforwardly with the
Matlab Compiler 4.3.

I read each file into my program by creating a text file
with all the file names (upwards of 700 files).  I read
each line of the text file with fgetl() command and was
wondering if there was a different, more efficient way to

I have an gui with some edit-boxes.
After starting the calculations via a pushbutton I save the
input of the edit boxes.
So when I start the gui next time I load the mat.file and

Is is possible to use something smaller than '.' when plotting:
plot(x,y, '.k')
Or is it possible to adjust the size of the marker?

Is there a possibility to set the system volume of WinXP SP2
to a predefined value?
I would like to set the volume at start of Matlab.
Thanks.

I defined two classes in Matlab: Asset and AssetData
Asset is as follows:

                 Greetings of the day!
I am new to ANN and matlab and as a project of M Tech I want to make a
crop yield forcasting system using Matlan 7.0.
The size of the train data is very small( I am using 19 years yearly

I have a masked subsystem and it has a "To Workspace"
block in it. To write the simulation result I have to give
a variable name in the "To Workspace" block's Variable
name: field.

I Have a gui file this gui connection with simulink ,
the simulink is power circuit I put prameters , I take
result and I run the simulink from the gui
I need to compile the gui to exe file ,I know how to

Could someone give me a hint on either of two related
questions:
1) (prefered one): how I can save 10 figures into a single
file? I am using a do-loop to generate the figures and
