Solving Ordinary Differential Equation with bvp4c Gives Error
I am trying to solve the first-order ordinary differential equation dy/dx = -sqrt(2*M^2*(sqrt(1-2*y/M^2) - 1) + exp(y) - 1 with boundary conditions y(0) = -2.84 + ln(M) y(inf) = 0 y'(inf) = 0 When I use bvp4c to solve this, I get the error "Unable to solve the collocation equations -- a singular Jacobi... 29 Jun 2010 17:23

C++ Tip : Binding a Reference to an Rvalue
http://learnbyexamples.org Rvalues and lvalues are a fundamental concept of C++ programming. In essence, an rvalue is an expression that cannot appear on the left-hand side of an assignment expression. By contrast, an lvalue refers to an object (in its wider sense), or a chunk of memory, to which you can write a val... 29 Jun 2010 19:36

Dear all, I need your help to read a unfriendly formatted ascii file which contains some data I have to analyze. The file looks like the following (delimiter is a number of blank spaces not tab): header 1 header 2 .... header N 10:39 data11 data12 data13 data14 data11 data12... 30 Jun 2010 09:45

Time series problem
I am relatively new to MATLAB, and just can't figure this one out although it is probably easy. I have a data set in which the date is of the form yyyymmdd, and use the following to convert it into a MATLAB date: date = datestr(datenum(sprintf('%d',day),'yyyymmdd'),'mm-dd-yyyy'); This only returns a date for the fir... 29 Jun 2010 17:23

Frequency/Wavenumber
I am working with seismic data and I need to do a frequency/wavenumber calculation. I have written the code but the code runs for a long time and I have a large data set to sort through. I was told that I can compile my m-script and create an .exe file. I have done this, but every time I try to run the file, it says... 29 Jun 2010 16:17

USB loadcell
I have begun playing with a minni USB loadcell (Futek Inc) and the software that came with it is less than desirable (tare, peak, current reading). I'm sure there is a way to read the data into MATLAB so I can store trials and play with them at a later date. Has anyone done this before, any tips, sample codes or even... 29 Jun 2010 15:10
