Optimisation toolbox
I need assistance on formulating a suitable objective function for optimisation using the optimisation toolbox. The objective function is to be based on ANN simulation Results. Can I possibly build an objective function of the form: y = Sim(Net,p) where p is a matrix of a range of parameters? ... 12 Jul 2010 19:37

'surf' deals with NaN
I was trying to use matlab command 'surf' to plot a matrix (app. 50*50). There are a lot of points with zero values and I do not want them to show up in the graph since it will give a wholly blue background for all of these zero values. I tried to replace all these zero values with NaN, but after this most of the value... 13 Jul 2010 12:00

rotate/flip image
Hello all, I am an undergraduate intern who was given a program that processes HDF5 images to TIF images. The program works in a way that it goes through image by image, one at a time. My task was to modify the program to go through an entire batch of images as well as rotate them 90 degrees (clockwise) as well as f... 13 Jul 2010 07:36

Signal Processing - Diversity Techniques
Hi All, I am working with a digital data collected from two GPS receivers and I need to apply different diversity techniques to see how Signal-to-noise ratio (SNR) could be improved. Data collected comes in numeric values which I believe represent amplitude. I was wondering if you could help me to get started by ... 12 Jul 2010 18:30

Need help with random selection of wav file in listbox
Ok so I have a project that I am working on and I am very new to matlab so I hve been doing a lot of trial and error. My project is to build a player that will take in a wav file "word+noise". I put in a db gain that I want to increase/decrease the noise by if the patient get the response correct or not. For the most p... 13 Jul 2010 13:07

Please help me produce a nice .eps or .pdf using pcolor
Hi - The problem you mentioned (the "white crisscrossed lines") frustrated the hell out of me for a while. As far as I can tell, the problem lies not with MATLAB's image rendering but rather with the anti-aliasing routine used in most PDF/EPS viewers. In other words the output from MATLAB is fine but the PDF viewer... 12 Jul 2010 17:23

CAN-USB Communication
Hi All, I have a ESD CAN-USB-mini. I would like to use MATLAB to communicate with it. I have a GUI which is used to control motors. This CAN-USB is suppose to send commands to the board that controls motors (AC/DC motors). I just don't know how to send command to this CAN-USB. Can you please tell me, how can I ... 12 Jul 2010 17:23
