Simulink Neural Network Modelling hi...I am my M.Tech. project now, and for this I need first to build a Neural Network based Simulink model. The training data is available. I need to give different nominal as well as faulty patterns of data to the model so that it can classify later a new dataset as good or faulty. I am new to Simulink. So can any... 11 Mar 2010 07:48

noob: 3D plot with colour as 4th dimension? I have recently stated using MatLab and have come across a problem with plotting: I have data [x,y,z,gain] and would like to represent this on a plot of some sort. What I am thinking is a 3D plot of (x,y,z) where the colour of that point is defined using a colormap (hot) for the value at that point. Is thi... 11 Mar 2010 07:48

USB & FTDI & Compiler Thanks Doug for this trick for handling void** using Matlab calllib function. It works well for me with Matlab R2007b. I use Matlab as a debugging tool for data processing within a dsPIC33. I am used to access DLL using a mex wrapper but I tried your solution which is faster than writing a mex for each individual func... 11 Mar 2010 04:32

interplation problem for a 2d matrix with some null points I have a table of data. The table is 2d and evenly spaced in x and y directions. However, some values of the table are lost and I must interplate using the available data points. e.g.: x = 1:4; y = 1:3; data = [ 0 1 1 2; inf inf 3 1; 2 0 inf 1]; T... 11 Mar 2010 04:32
