Now, when I reinsert the installation DVD, it spins up, copies the files to the temp directory, displays the MATLAB logo and then nothing. MATLAB is not on the list of installed programs to uninstall but it seems like my sy... 4 May 2010 23:31

Explicit Solution Can't Be found
I'm having problems solving 2 equations simultaneously in matlab. I think the problem is the combination of sqrt's and squared variables. Its probably simple, but my programming knowledge is pretty limited, so any help would be appreciated. heres the simplified part of the program I'm trying to solve right now - ~... 5 May 2010 00:38

export a cell of strings as a text file
Hi there, I need to save a cell (1000 by 6) as a .txt file. Each of the columns has strings, for example: testcase = 'one' 'pre70' 'Wood' 'Gable' 'Shingle' 'less100k' 'one' '1971-1984' 'CB' 'Gable' 'Shingle' 'less100k' 'one' '1971-1984' 'CB' 'Gable' 'Tiles' ... 5 May 2010 12:38

Ode 15s
I need to solve a system of coupled nonlinear equations of the form: a11*u(1)+a12*u(2)=0; du(2)/dt= b11*u(1)+b12*u(3); du(3)/dt= c11*u(1)+c12*u(2)+c13*u(3); where u(1),u(2) and u(3) are unknowns whose values at t=0 is given. a11,a12...b12..c11,c12... are constants and values are know. How do I use ode15s to so... 5 May 2010 03:51

Conversion to cell from double is not possible - Error
Can someone help me with this problem. I'll post the instructions, and the code I've created. Given the following equation: y=1/ sqrt [1+(αt)^2] where 0 ≤ α ≤ 2 and 0 ≤ t ≤ 5. We would like to see how the plot of y vs. t changes as the value of the parameter α changes. This is to be done in the foll... 4 May 2010 21:17

compiled exe missing data, no ctf file
I am getting varying results when I run the mcc compiler with the 'Embed CTF archive into the Application' option turned on (create_CTF = false) - sometimes the produced exe is about 1 1/2 mbytes and all is good (the exe runs as expected), and other times the exe produced is only 36 kb (vastly smaller), and of course i... 6 May 2010 15:22

Tools for the Daylight Saving Time?
Unfortunately, this is not as easy as it seems. It is pretty easy to get the dates where you spring forward or backward (http://www.timeanddate.com/worldclock/timezone.html?n=234&syear=1970) but there is no way to know if 1:00:00 AM through 1:59:59AM on the Fall back day is Standard Time or Daylight Saving Time.
