simple neural network problem
Hi I am new to neural network. I am reading a book which gives me some general idea. I still have three quarter of the book need to read. However, may I know how neural network handle a time dependent pattern recognition. For example, how to use neural network to classify BIO signal? any website/ information will ... 23 Jun 2010 13:57

C-scan Image construction
Dear Rune, Here is the short description of what A-, B-, and C-Scan means: A-, B-, C-, Scan usually refers to the method of representing an ultrasound signals. A-scan displays the amount of received ultrasonic energy as a function of time. Relative amount of received energy is plotted along the vertical axis an... 23 Jun 2010 13:57

Problem with fzero and maxiter option
I'm trying to use fzero(f, x, options) to find a zero of a function and limit the maximal number of iterations. I set 'MaxIter' option to 500, however, fzero seems to ignore this and iterates until it diverges to infinity. This link: http://programming.itags.org/matlab/46258/ seems to indicate that maxIter doesn't w... 24 Jun 2010 08:30

scatter plot for three variables
hai all there i have one variable say 'a' which has 10 rows and 2 columns. i.e, there are 10 instances of 2 dimentional. similarly i have anothor two variables, 'b' and 'c'. all are having 10 instances, in two dimensions. or simply , a=rand(10,2); b=rand(10,2); c=rand(10,2). i want to plot these a, b and c on... 25 Jun 2010 02:15

The Compatibility of struct() with VHDL
Hello, I am trying to make my own JPEG baseline codec and transfer it to VHDL so that I could use it in my FPGA based design. I am wondering if MATLAB structured array is a transferrable feature for VHDL? What I am trying to do is to create the beatstream which has be formed using different size of codewords... 23 Jun 2010 13:57

FFT Plot labeling
Dear All, I have FFT plot (Freq. vs. Amp.). Can I produce same plot but as (Period vs. amplitude). Period is (1/freq.)? The problem is the plot does not accept values that is in ascending order (high to low) values. your help is greatly appreciated Thank you IA ... 24 Jun 2010 03:07

reading in a 3D image saved as .TIF
Hi, I have a somewhat unusual problem. I need to read in a volumetric image saved as a .tif file, but I cannot index the individual slices of the image, eg. imread('image.tif',slice_i), as the entire 3D array had been saved as multichannel image. So the only feasible syntax is imread('image.tif'), which by default r... 23 Jun 2010 12:50

block LDL decomposition doesn't cut it!
Matlab uses the *block* LDL decomposition rather than the "vanilla" LDL decomposition. In the vanilla LDL decomposition, the matrices L and D are lower triangular and diagonal, respectively. In the block LDL decomposition, L and D are "psychologically" lower triangular and "block" diagonal respectively. Unfortunat... 23 Jun 2010 12:50
