Decimation Problem I have some Signals about 500 samples acquired in 750 seconds.. so Row denotes time = 1:1:750, coulmns are 500 Now I need to remove time and columns having value of 45.....there are some..so need to remove indexes of both time and signal...... After that i need to run a algorithm say [x,y]=dft(time,signal)... 9 Aug 2010 16:47
Multiple Image to Matrix Conversion I have 1500 binary images. I have been trying to create a matrix that will have 1500 number of columns. Each column will contain all the image elements of an image. Here's the code I have been trying: function test tifFiles = dir('*.tif'); %takes all the images from the folder Sample for k = 1:length(... 7 Aug 2010 23:25
Saving a portion of pathname as a string? I have a pathname with the following: C:\Documents and Settings\LM Files\ALL\TEST_01\NEW\ I would like to save the 3 strings from this: var1 = 'LM Files' var2 = 'TEST_01' var3 = '01' Is there any way to do this using strread or something else? I have tried using strread, but have been unsuccessful. ... 9 Aug 2010 08:59
Plotting questions Hi. Im trying to plot some data using matlab like this: http://www.mtc.gob.pe/portal/transportes/aereo/examenes_licencias/examenes/diagramas/despachador/13.jpg Using grid, how to define how closely spaced the grid should be displayed? And is it possible to make the large grid line for each every eg. 5? Is i... 6 Aug 2010 21:28
Is there a "this" pointer in MATLAB? I've written a class with a method that I would like to use to change the value of several of an object's properties, rather than writing set functions for each property. Can I return a reference to the object which calls the method (the "this" pointer in C++), or is that not possible in MATLAB? Sample class: cla... 6 Aug 2010 17:05

angle between two vectors In 2-space, I have a three points: c, the ctr p, an arbitrary point, and v, a point indicating a direction (as a vector from the ctr to v). I need to determine whether the point p is in the forward direction of the vector v from the center point, c. I have gotten this to work by means of the law of cosine... 6 Aug 2010 14:52

Speeding up a complex exponential Hello, there. I have a code where the slowest part is to compute hundreds of time something like exp(1i*t*D), where t is an scalar and D is, in general, complex and best case scenario, real and bounded. Given that within my code, t will change randomly but monotonically (actually, this is a function integrated with ... 6 Aug 2010 15:58
Running matlab from xterm from a cronjob? (Matlab-xterm-cronjob); Hey Everyone, I am trying to run Matlab with crontab in order to produce pictures/graphs, on Max OS. I have read in the Technical Solutions that This problem may be able to be avoided using a VNC server. [( http://www.mathworks.com/support/solutions/en/data/1-1B3IT/?solution=1-1B3IT )]. So I have been attem... 6 Aug 2010 14:52 |
