Grouping values of an iteration in order to plot them
I am writing a program to plot an iteration over a time interval. When i run the program, all the values for 'ya' are printed in the main window and they all seem to be accurate. However when I try to plot the values over time, it only plots the last iteration value. I just wondered if anyone could help me find a way o... 9 May 2010 21:59

Poisson Equation Solving on Images
Hello All, Am trying to solve a poisson equation on image derivatives. Any idea on how to implement it in Matlab?? Here's what am doing. Laplacian(I) = divergence(Gx,Gy) Gx and Gy are 2D derivative images. I is unknown. and we are recovering I from known values Gx and Gy So if we expand the equation, for ev... 18 May 2010 15:53

Using ANN as fitness function in GA
I have a trained ANN and need to use it as fitness function in GA. ANN has three input parameters and one parameter used as an output. Also, it has one hidden layer with two neurons, and one output layer with one neuraon as default. I need to optimize one of the input parameters using GA. Please, can somebody help me t... 9 May 2010 14:19
