In particular, i have a 3d rendering of a brain in a figure and a set of points in the other figure.These points are registered with the brain surface and i want to visualize them on the brain rendering(in their exact positions).... 9 May 2010 02:29

Mex compiles but fails in execution
Hi all, I had to create a MEX file from C code, using external libraries, and also installing Microsoft VC++ compiler. I have succeeded compiling the MEX file, after linking all the libraries, solving problems with DLLs and this stuff. The MEX file is hence created. When I call the MEX file, Matlab claims it ... 5 May 2010 18:15

ode with boundaries
hi, i want to force my ode45 solver to search for a solution (good enough time step) only within certain boundaries imposed on one (out of tenths) of the differentiated parameters. is there a nice way of doing it? by 'nice' i mean not letting the solver to try values of the parameter outside the range (and throwing th... 4 May 2010 07:53

ODE system and derivative.
Hi everybody, I'm using Matlab solvers to solve an ODE system. I'm wondering if there is a way to get as output not only the solution of the system, but also how the derivative defining the system change with time. I mean I'd like to know also the values for dydt as evaluated by the solver, is there any option ... 4 May 2010 12:19

How to sort a 2-d matrix
Hi everyone I'd like to know if there is any instruction in matlab to sort a matrix like this example: X =[ 0.506 0.258 0.478 201 203 202] x_sorted = [0.258 0.478 0.506 203 202 201] What I am looking for is to sort the first row in ascend way and moving the value on the... 4 May 2010 08:58

batch mode
Hi all, I am running matlab in batch mode under linux via ssh (without X11 forwarding). The call statement is something like this: matlab -nojvm <myscript.m> myout.txt & This works fine and I am able to check the progress of my simulations by checking the txt file. The problem is that the script could have funct... 4 May 2010 14:33

header in matrix
Hey, I'm exporting a matrix with dlmwrite to txt. Now I'm trying to set a header on top of it.. something like the example here: text = [average, std, cv, min, max] data=[ 10, 5, 3, 1, 10; 10, 5, 3, 1, 10; 10, 5, 3, 1, 10; 10, 5, 3, 1, 10;] the output should look like: ... 4 May 2010 12:19
