Glass Passivated Rectifier
I'm trying to represent a fairly simple circuit in Simulink. One of the components is a MUR 440 Ultrafast Glass Passivated Rectifier. Searching in Simulink, the only blocks I find are 4 different Rectifier DC Motor Drives. However there are more ports than I need for this application, and I'm wondering if there is a... 8 Jul 2010 21:26

Classifying Pulses, Sinusoids, and Noise
I need to build a robust detector of pulses and sinusoids in a background of noise. In most cases, the signal to noise ratio is greater than 1. http://spikehound.sourceforge.net/pulse_sine_noise.png That link has an example of the signal I'm trying to break apart into classes. For each point in the signal I'd l... 8 Jul 2010 21:26

How to plot time domain sparameters(t_params)
Hello, Does anyone have any ideas how I will plot time domain sparameters(t_params) from the code below. %Define a matrix of S-parameters s11 = 0.61*exp(j*165/180*pi); s21 = 3.72*exp(j*59/180*pi); s12 = 0.05*exp(j*42/180*pi); s22 = 0.45*exp(j*(-48/180)*pi); s_params = [s11 s12; s21 s22]; %Convert to T-param... 8 Jul 2010 20:19

Formatting the Dates on imported data
I was wondering if anyone could help with formatting a huge amount of data that I have? The data that I will be formating is the date and time that a bunch of sensors were activated. The format of the raw data is yyyy-mm-dd hour:min:sec and I need to change it to dd-mm-yyyy hour:min:sec. I have been trying to cha... 8 Jul 2010 19:12

colorbar title
If you have already made a colorbar and want to find the handle to the colorbar axis so that you can set the properties. This works: ax = findobj(get(FIGUREHANDLE,'Children'),'Tag','Colorbar'); or ax = findobj(get(gcf,'Children'),'Tag','Colorbar'); %if it's the current figure ... 8 Jul 2010 19:12

Butterworth filter
Hi, I am new to Matlab and am trying to write a butterworth filter. Matlab help and Google gave me some indication as to what the code should look like but I still dont understand why it does not work. I am attempting to use a band pass filter to remove 1 frequency from a mixture of sine waves. % bandpass filter ... 8 Jul 2010 20:19

inverse prediction for logistic regression?
Hi there, Is there a straightforward way to do inverse prediction for a simple logistic regression in MATLAB? I've used "glmfit" with the binomial distribution to fit my data and now I'd really love a simple command for getting the X (predictor) value resulting in a 50% probability value for the response.
