colors for individual contour lines
Can I control the colors for individual contour lines using "contour". If I specify the color all contour lines come out with the specified color. If I do not specify the color each lines comes out with its own color. My problem is that the colors vary with the range of the contours. Is it possible to specify (... 16 Apr 2010 15:05

Fast Delaunay neighbourhood calculation
Hello, Imagine I have a n*3 matrix Positions of cell positions in space. I did the following to extract the Delaunay triangulation and the neighbourhood relationships implied by it (0 if stranger, 1 if neighbour). Is there a way to do this faster ? What if I wanted to take away unlikely relationships, e.g. betwee... 16 Apr 2010 06:09

Logical indexing in matrices
Hello, This is what I am trying to do : I have an n*3 matrix of cell velocities in space 'Velocity' and an n*n logical matrix of neighbourhood relationships 'Neigh' (0 if stranger, 1 if neighbour). n is about 5000 to 10000. Some speeds are NaN. To average speed in space, I did the following : AverageVelocity=... 16 Apr 2010 21:46

Hi, I am running a model in simulink. But when ever i run the model i.e start time 0 and stop time 10. It runs it from 9 to 10. I have given a fixed step size of 0.00001. And also if i give a step size of 0.000001 my system hangs or gives the error not enough memory. Can anybody tell me where is the problem? Rega... 16 Apr 2010 08:21

can someone help me with the constrained optimization ?
please help me. what is the correct way of writing/supplying the upper and lower bound of my minimization problem? for example i have 4 design variables in which all of them have the bounds of: 10<= x(1)<=15 10<=x(2)<=15 0.1<=x(3)<=0.25 1.0<=x(4)<=2.5 plus the inequality constraint of: c =(P/(x(2)-2*x(4))*x(3)) ... 16 Apr 2010 11:41

Creating a matrix of strings?
Hi! I am trying to store some words into a vector/ matrix. I noticed that they are treated as chars in Matlab. So, my questions is: is it possible to get a particular word (string) instead of char? To be more clear, here is example: columnNames = ['TOTSPACE','LIVSPACE','KITSPACE','DISTKM','ROOMS','BRICK']; I wo... 16 Apr 2010 05:05
