Real Subscript Indices
Hi, I'm doing a loop from "i"=0 to 0.5 with steps of 0.01. (0:0.01:0.5) For every "i", i'm putting the maximum likelihood value I calculated into a matrice. In order to have real indices, I multiply "i" by a hundred and add 1. (100*i+1). By doing this, I end up with indices of 1,2,3,4,.....,51 which is allowing m... 19 Jun 2010 13:27

how to calculate discrete transfer function
My function is K/s. I have calculated in discrete transfer function by hand which comes to be KT/(z-1) I want to cross check in Matlab and want to calculate its value at T=.1 What are commands for that ... 19 Jun 2010 14:33

3D plot
Hi. This will probably sound mundane but how do I plot a 3D graph with data imported from excel? I have only recently started using MatLab and do not have much knowledge about it apart from some very basic usage. I imported the data and separated them into data1, data2 and data3, without using xlsread though. They a... 12 Aug 2010 12:33

Updating positions on points in a plot "on-the-fly"?
"Adam Hartshorne" <adam.hartshorne(a)gmail.com> wrote in message <hlhr31$3l1$1(a)fred.mathworks.com>... As far as I am aware. If I put a break clause in order to observe the workspace, it show the various variables required. I have also tried, refreshdata(obj.h) with the same result. Hi Adam, ... 19 Jun 2010 11:16

Log all Fixed-Point operations
I am using matlab's filter function using their Fixed Point library. Is there a way to log *all* fixed-point operations? (not only overflows, but all fixed-point operations) Thanks, David ... 15 Jul 2010 09:51

fft algorithm.
Hello there. I have just implemented a 3 phase PWM DC/AC converter in Simulink using IGBTD with a "RL" load and I have to write and algorithm to show the Frequency domain. I don't really know how to do it.I have just try to write something down onmy M-file which is: % tstep = t(2)- t(1); % fsample = 1/tstep; % time... 19 Jul 2010 16:52

Massive difference between running simulink from GUI and command line. Why?
Hi Folks I am having a curious problem with simulink. I am running a model via the GUI and the command line. IN the first case I am passing the inputs via simulink blocks with the required signals, and setting the intial conditions via the Interface. In the second case I am sending the inputs via an input port, and ... 19 Jun 2010 08:00

Modelling the speed of a DC Motor with LMS
Hi guys I am having a research on adaptive control though FIR filter and LMS algorithm and I need to model a DC motor with the speed as its output variable. Can I obtained a model of a DC motor with the speed as its output through FIR and LMS algorithm in Simuling and using NI DAQ. Thanks and have a good day. ... 19 Jun 2010 05:52

storing specefic data from multiple frames in a text file
Hi, I want to read 50 images from a folder and extract some specific features from each frames by applying an image processing algorithm and store the feature vector for a particular frame in an apt data structure. After that, I want to store all these feature vectors (equal to the number of frames) in a text file and... 20 Jun 2010 10:11
