color a 3D line Dear All, I have a relatively simple problem I'm struggling with. I want to render color to a 3D line (i.e. a bunch of 3D points connected by a line - please refer to the end of this post for the eg.). Now I'm trying to give each line segment connecting consecutive 3D points a color based on their gradient (finally the... 24 May 2010 01:32

Concatenating matrices alongside diagonal Hi folks, is there any command / efficient way that would help to arrange square matrices of one size into a big one so that they are on the diagonal and all elsewhere there 'd be zeros? a, b, c .. are (n,n) e.g. n = 2 BIG = a11 a12 0 0 0 0 a21 a22 0 0 0 0 0 0 b11 b12 0 0 0 0 b21 b22 0 0 0 0 0 0 c11 c... 24 May 2010 13:27
transform vector in matrix with more elements Hi all, I'm looking for a fast way to distribute vector elements in a given matrix such that identical elements are listed in the same matrix row; the tricky part is that the vector has fewer elements than the matrix. For instance, assume that I have vector A: A = [1 2 2 3 3 3 4 4 4 4 5 5 5 5 6 6 6 7 7 8] I n... 25 May 2010 08:00

garchpred ARIMA models Hello, Does any one knows where can I find examples of ARIMA forecasting? I am wondering if it is more appropriate to use MeanRMSE instead of SigmaTotal (outputs for garchpred) to form predictive intervals. According with my bibliography, we should use MeanRMSE but I have seen pepole using the standard deviation of ... 23 May 2010 17:56
interp1 function Hi all, the interp1 function is used in reading off the values of the y-axis by providing the x-axis. Is there a way to do the reverse? I.e providing the values on the y-axis and having the function give the corresponding value on the x-axis. Thanks for your contributions Charles. ... 25 May 2010 10:11 |
