**Need help with the ideal gas law.**Ladies and or Gentlemen,
I have a CO2 Gas Concentration expression:
[CO2 concentration] = (-(ln (1 . (1 . Ratio/zero)/span)) / a) ^ (1/b)
Where Ratio is the ratio of active to reference peak to peak signals and is
essentially independent of variations in source intensity over time. This
ratio reduces in the presence of target gas. It is the reduction in this
ratio that is used to determine the target gas concentration. The reduction
in ratio is non-linear.
Where zero is the ratio in the absence of target gas.
Where span is determined during calibration and
a = 0.0005989...

**Problem in solving a problem by matlab.**Hello Everybody,
I am having a problem in back propagation network. It is not
a direct one to use sofwares like matlab for simulation. The problem
is briefly described as follows.
I want to specify the number of interconnections in the
hidden layer or between the hidden layers. Can this possible using
Matlab? Also I want to share the weights between two sets of hidden
layers how to do that in Matlab?
Please suggest me any other GUI softwares that can solve both
the above problems or give me suggestions or atleast the posibility of
doing this in Matlab(any...

**Matlab 7**I have Matlab 7.0, including Matlab Web server (ver 1.2.3). I have a
problem using it. My computer is XP Prof (SP2), Pentium 1GHz.
This problem does not occur with Matlab 6.5.
The Matlab server is executed from a Web page and it launches Matlab
7 functions. The Matlab functions compute results and display these
(using Matlab server) on other Web pages.
The problem and observations are:
1. After the server-launched Matlab finishes its work, if I open a
new Matlab 7, this runs very slowly because it uses up more than 80%
of computer CPU (and about 60MB memory).
2. The launched Matlab, even af...

**problems when changing from matlab R2007a to matlab R2008b**Hi all,
I have problems when changing from matlab R2007a to matlab R2008b. I have a simulink model running in R2007a which i use to obtain certain results. Nevertheless, these results are differents when i try to run the same simulink model in R2008b. I have done nothing different but running the same model in the new matlab version. I don?t know if i have to change some configuration parameter connected to the new matlab version. If someone could help i would appreciate it.
Thank you

**Problems calling from Matlab a Matlab compiled dll**Hi,
I'm trying to make a dll from an m-file and use the dll function calling from the workspace or from an m file using 2008A version:
Step 1
function [output] = addizione (a,b)
output = a+b;
end
Step 2
I compile it with matlab compiler
mcc -l addizione
I obtain
addizione.dll, .lib, .h etc
Step 3
load the newly created addizione.dll
loadlibrary ('addizione','addizione')

**problem saving plot as jpeg and problem with matlab webserver**Hi,
I have made an application that plots a figure. I am trying to use
matlab webserver to send the data to an html file.
The problem is that I want to save the plot as a jpeg file. I used
the following code taken from various examples.

f = figure('visible','on');
