help in time series prediction by neural networks
Dear friends . I have gone through the manual of NN Toolbox but I found nothing about the use of neural networks for forecasting of univariate and multivariate time series. Could anybody tell me where can I find examples of this kind of applications? This is a new subject for me and I need to start with something ... 12 Mar 2010 11:38

MUPAD - big ODE
So I am trying to find the equation of motion for a system, using Lagrangian mechanics. MUPAD has solved it for me, but when I ask it to differentiate something, with respect to t (time), it makes all my constants functions of time, and therefore doesnt set them to 0 if they are constants F:= 2r differentiated ... 12 Mar 2010 10:31

Zero padding - CUDA vs MATLAB - fft2() vs CUFFT
Hi, I am trying to convert a matlab code to CUDA. In matlab, the functionY = fft2(X,m,n) truncates X, or pads X with zeros to create an m-by-n array before doing the transform. I would like to perform a fft2 on 2D filter with the CUFFT library. I did not find any CUDA API function which does zero padding so I implemen... 15 Mar 2010 10:04

Dobbelt integration when inner integral is ^2
I am calculating the damping force of a permanent magnet. The damping force is called F in my code. F is calculated as a dobbeltintegration over to variabels y and z1. The problem is that the inner integral (variable z1) needs to be ^2. The integration I would like to perform looks like this: F= constant*int(int(... 15 Mar 2010 10:04

3D Matrix access in Mex files
Hello, I have an issue I am not able to overcome. I want to create a mex file and pass to it a 3D double matrix representing an Image, for instance inputImage[480,640,3]. I cannot understand how to access the element of the matrix inside the mex files, I have tried everything with pointers with no results at all, it... 15 Mar 2010 16:58

Paper currency recognition using hidden markov model
