Hi, I'm trying to predict the next point in a time series using wavelet decomposition and neural networks. But I'm having problems choosing the data to feed the NN after the signal decomposition. Can anyone clarify which data should train my network? Thanks, Bruno ... 25 May 2010 17:57

Plot Error Bar graph
Hi there, I want to plot error bar graph for categorical graph, example meanForGroup1 = 4.3; meanForGroup2 = 4.9; stdevForGroup1 = 2.3; stdevForGroup2 = 2.5; The graph should be an error bar graph: two error bars for group1 and group2, centering at means and ranges as +- 1 standard deviations for group1 and g... 24 May 2010 23:26

index manipulation... shifting and rotating
I know there are functions like rot90 to rotate a matrix about a point, but you need the the matrix. I only have the linear index values of the matrix. I can easily shift the indexes by adding or subtracting either row or column values... but what if I wanted to rotate by 90 or 180 degrees... is this possible with ju... 25 May 2010 19:04

String Manipulation
Hello All, I have some data in a file of which some comes under Log Peak-Valley Data whereas the other comes in Log Timed data. I want to read the data only from Log Peak-Valley data and ignore the one from Log Timed data and other paramters also as given below. I have got the code for extracting all the numbers ... 25 May 2010 15:45

[Simmechanics] build spring damper mass system with nonlinear
I am currently trying to build following EOM by using Simmechanics. m*x_doubledot + b*x_dot + k(1-e^(-x))=0 I am facing difficulty due to third nonlinear term. Anyone shows how to build this to get x , x_dot and x_doubledot? Thank you in advance! ... 24 May 2010 21:15

Euclidean distance
