How to Plot this Kind of Matrix
Hello to everybody! I have to plot a matrix 10111 x 3 where the first two columns are the points' coordinates and the third column is the value of the point. With that matrix i have take a grid to approximate the plan's portion [0...10,0...10]: 0 0 -0,162093682194603 0 0,1 -0,165728548002140 0 0,2 -0,1677556079902... 2 Aug 2010 10:19

Help needed: VideoCompressor property of video.MultimediaFileWriter

.bash_profile
I'm using 2010a on an Intel Mac. Previously, I had trouble getting Matlab to find things in my Unix Path, which I figured out how to fix when I started this thread: http://www.mathworks.com/matlabcentral/newsreader/view_thread/255609 I'm not actually doing that anymore. Instead, I have the following lines in my... 3 Aug 2010 13:38

Binary to fixed point, HELP !!!!!
Does Anyone knows how to convert a binary number to fixed point number specifying integer and fraction bits ?? for example , I have the binary number 11101 and I need to convert to fixed point with 1 integer bit and 4 fraction bits: 11101 = 1.825; Now, using the same binary number I need to convert to fixed poin... 2 Aug 2010 10:19

GMRES and preconditioning
Can anyone provide some information about how the implementation of GMRES in Matlab uses preconditioners? I am testing an initial-boundary value problem solver where I have a differential operator A and a preconditioning integral operator M with functions that apply these matrices to given vectors. I thought GMRES solv... 2 Aug 2010 09:13

cross-tabulation, contingency table
Hi, just going through old code and trying to make it more efficient. Hoping for some good suggestions... Say I have an array: x = 1 0 1 1 1 1 2 0 2 1 4 0 4 0 Thus should give a contingency table of: 1 2 1 1 0 0 2 0 However, the function 'crosstab' would give the answer: 1 2 1 1 2 0 I ... 2 Aug 2010 08:08

Direction vector in phase portrait
Hi I'm creating a phase portrait by running a loop with different initial conditions to get 10 trajectories and show the stability of the different fixed points. I therefore want to place an arrow in the direction of the flow on each trajectory, but only on the trajectories so quiverplot cannot help me. I'm sure ... 2 Aug 2010 08:08
