AR, Burg methods worse resolution than FFT Hi, I've been told Autoregressive Process (AR) offers better frequency resolution than classic Periodogram methods. So I used an example available in the MATLAB manual and compared with Periodogram. Results showed that Periodogram had better frequency resolution than AR via Burg method. I also studied pyulear, pc... 9 Aug 2010 14:33
How to save files into a specific folder hello, I am working on a dataset of movies, and each set contains 9 videos, so i am willing to save the frames of each video in a separate folder, can anyone help me on that?? I would be very greatful. bellow is the code I am using, but this help only to save the frames of first video of the set into 'jpg' files, but ... 8 Aug 2010 12:18
An exact simplification challenge - 104 (EllipticF, Log) Hello, At all positive integers n >= 2 n EllipticF[ArcSin[Sqrt[2]], 1/(1 - n^2)]/Sqrt[n^2 - 1] - n EllipticF[ArcSin[Sqrt[1 + n]], 1/(1 - n^2)]/Sqrt[n^2 - 1] + EllipticF[I ArcSinh[Sqrt[n]], 1/n^2] - EllipticF[I ArcSinh[n], 1/n^2] = ?

Erratic Error using legend while plotting Hi, I'm trying to add legends to a plot using a dynamically assigned string array that is being updated in every iteration based on certain condition. However, I see an erratic behavior while using legend. Sometimes it runs successfully without any error (even when a varieties of legends are present in different plo... 8 Aug 2010 22:11
DLL Header Hi I am new to calling DLLs from MATLAB. I have a third party COM DLL that I will like to work with in MATLAB to receive some feeds. I have the API and some examples in C++. I am having problems using loadlibrary. I have search through the newsgroup to get a solution. Unfortunately no luck yet. I am hoping someone w... 7 Aug 2010 15:49
Passing C-allocated array to Matlab in mex I have a C library that dynamically allocates some arrays. One function is called by a mex function and I wish to pass these double arrays to Matlab without duplicating the arrays. I currently do plhs[p] = mxCreateNumericMatrix (1, 1, mxDOUBLE_CLASS, mxREAL); mxSetData (plhs[p], (void *)my_array); mxSetM (... 7 Aug 2010 16:54
extension g I have an old file that I have received 7 years ago that has an extension "g". I didn't need it then but now i need the info and I am enable to open it. Also, the one who sent it is unreachable. All I know is that the data is in matrix format. IS there a way to open this file with Matlab? ... 8 Aug 2010 13:24

Time Series Forecasting Hello! I am new at Matlab, and I need to do Time Series Forecasting. More specifically I have daily movie ratings until a date and I need to predict ratings from that day on(I suppose it has to do with time series forecasting, right?) Until now I have only imported my data from a MySQL database and created some ne... 8 Aug 2010 16:43
Calculate the coordinates of the 3rd vertex of a spherical triangle knowing the other 2 vertices, angles and edge lengths I have two points on a sphere (x1,y1,z1) and (x2,y2,z2) that are vertices of a spherical triangle (I considered a sphere of center (0,0,0) and radius 1). I need to know the coordinates of the other 3rd vertex of the spherical triangle. I know the three angles of the spherical triangle and also the three edge lengt... 10 Aug 2010 05:50 |
