PDE Toolbox, partial profiles of solution
Dear members, imagine one received a solution U(y,z) by the PDE Toolbox over a 2D-domain Omega{y,z}. It means, we know U_{ij} in certain knots of Omega. My problem is to get U in a certain cross-section of Omega with a vertical plain a*y+b*z=c? Example: Omega is a rectangle {-a<y<a, -b<z<b}. We may wish to see th... 19 Feb 2010 14:22

is there a name for this and/or perhaps
a matlab function? I have a vector of data DATA and also respective X and Y coordinate vectors of the same length as data. I need to divide my area into rectangular boxes and then calculate the mean (based on my DATA) for each of these box. Is there a function like that in Matlab? Thanks ... 19 Feb 2010 15:30

Controlling different movements in simmechanics
I have a question concerning the control of different movements during a simulation using primarily simmechanics. Imaging that I have a body (A) (CS1: [0 0 0] and CS2: [1 0 0] parallel to the world's x-axis. Perpendicular with that body I have a second body (B) (CS1: [1 0 0] and CS2: [1 -1 0]. Bodies A and B are attach... 19 Feb 2010 12:05

plotting a piecewise continuous function
I am wanting to plot a piecewise continuous function, I am not able to find the correct syntax to do this. Here is a simple example that should give a triangle centered at x=0, f(x)= { 1+x -1<=x<=0 { 1-x 0<x<=1 This is how I am incorrectly trying to do this (it seems others suggest this approa... 19 Feb 2010 15:30

Matlab complied llb and LabVIEW
Hi, I would like to compile a small .m function for use as a llb in a LabVIEW vi. I have tried a few things but can't get the thing to work. The code (see below) compiles and crates a dll etc. and I can link to it in LabVIEW, but nothing happens. function [c d] = adder (a,b) c = a + b; d = a - b; Does anyone... 19 Feb 2010 12:05

adjacency matrix for a graph
Hi guys, I am trying to find the adjacency matrix for a graph A=(aij) which is constructed through this rule: aij= 1 ,if there is an edge connecting Pj to Pi. 0 .otherwise. The graph has ten 10 vertices : P1,P2,....,P5. So, the dimension of the matrix is 5x5. clear n=5; % n= no. of vertice... 19 Feb 2010 10:58
