**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

**Matlab problem!!**Dear All
I hope that you are doing well and everything is OK.
I have a question, please:
I have a decimal number stored in a matrix. For example,
Matrix subscripts: 1 2 3 5 6 7 8 9
10
Values: 8 9 8 7 7 9 9 2
7
So, the number is: 898779927
My matrix consists of 3000 cells and each cell contains a number from
0-9. I need to get the number of bits for this string in binary.
However, I cannot convert it to binary as the program will give me out
of range.
Thanks and your response will be much appreciated.
Sincerely,

**Problem with matlab**I have to find the period of a certain periodic waveform that is make up of data points of a matrix Y. This matrix has a total of 27881 rows and 7 columns. The 2nd column and the 4th column is the y axis data points and time data points respectively.
The method i did was to do a loop to get the index that represents the max peak value. The problem is that i am umsure how to start another loop counter from the last index value that is achieved from the looping that i have used earllier. Here is the codes. Coz to get the period i decide to use the peak to peak approach

I am facing a strange problem with MATLAB. I have a function
prolate_legendre_expansion.m which behaves as follows.
If called at the MATLAB prompt, for example as

it works fine. However, if this function is called from within another

**Why did Matlab have problem on this ?**I have ML 7 .1 and it has problem on my computer on this equation (no
error, just takes all the cpu power and I have to manually end the task
)

Do you want the CPU on our computers to be consumed as well ... ?
Try each of the parts in your expression separately until you find the
root of the problem :)

**A problem with matlab**Hi, folks:
I have a problem with the running of a matlab software under Windows
2000. The problem is that when I double-click the matlab executable
short-cut on the desktop, the software first searches the
documentation disk on the default CD-ROM, but I donot have the
documentation disk in my hands. As a result, although I have a
well-installed matlab in my computer, I can't run and use it
successfully. So I appreciate that someone email me the detailed
solution so that I can run matlab without the documentation disk.
Thanks,

me, i could be wrong about that assumption) . Then i reset and it all works

If you post the code that you've started with and explain exactly where
you're getting stuck, we may be able to help you. We don't want to rewrite

**Problem with a problem**Hello,
take a grammar G with alphabet {0,1} such that (the word problem for)
the language
L_G={w in (0+1)*|w\in L(G)}
is very complex, say in PSPACE or some higher complexity class.
Now consider an "easy" problem EASY like: "Is an element of L_G in
L_G?". Well, this seems to be fairly easy because the answer is "yes"
in any case. Hence the problem should be of small complexity.
But if one models such a decision problem one has to construct a
language L with alphabet A such that the word problem for L reflects
exactly the decision problem which one is interested...
