using matlab as a solver
Hi i have the function ((((ERFC(x/(2*(SQRT((0.0101)*t))))))-((EXP((8*x)/6.7)+((64*(0.0101)*t)/(6.7^2)))*((ERFC((x/(2*(SQRT((0.0101)*t))))+((8*(SQRT((0.0101)*t)))/6.7))))))= T(x,t)-Ti/To-Ti Can I use matlab to solve? ... 28 Apr 2010 16:17

Fast calculation of velocity from x & y data
Hi, I searched but couldn't find an answer to this. I'm running an analysis on x&y data. The program is long, but one section of code takes up the vast majority of the time. Here it is: clear hypotenuse for i=1:length(t) hypotenuse(i) = sqrt(x(i)^2 + y(i)^2); end clear rawvelocity rawvelocity(1)=0; ... 28 Apr 2010 16:18

dct2 important
Hi everyone, This is how I am trying to inplement the dct2 function using the equation for dct. I am not able to understand why the program runs into an infinite loop when i execute the code. Pls let me know where the error is and how I can enhance the speed of the program... Also I see that when I reduce the size... 28 Apr 2010 15:08

Embedded matlab recursion
Is there workaround for the no recursion in embedded matlab, I would really like to implement a recursive function but It won't let me. Does anyone have a workaround or even a reason why this constraint exists? ... 29 Apr 2010 11:14

can you omit "handles." prefix?
While it may be unsafe programming, I seem to generate a lot of code which would be far more readable without having to explicitly refer to the handles i'm passing. I'm looking for one of the side benefits of c#'s "using" statement I suppose. An example: Instead of: handles.sqs(i) = handles.fs * 10 * handles.i... 28 Apr 2010 14:00

Legend
I've got function plotting about 30 different functions on a single figure. However I only want my legend to represent the last two plots. Can this be done? And putting the last two functions being plotted at the start of my plot order does not work, because I need them to appear on top of the other plots. Than... 28 Apr 2010 14:00

pseudo inverse of rank 1 or rank deficient matrix
while evaluating the Bit Error Rate in a fading channel we equalize the received bits before demodulating. so we multiply with the pseudo inverse of the channel matrix. what will be the pseudo inverse of a rank 1 matrix ie rank deficient matrix ? I am evaluating BER for BPSK in a keyhole MIMO channel. Regards, P... 28 Apr 2010 14:00
