Hi,
I have some Matlab functions defined in .m files and I'd like to import them into Matlab (as in I'd like them to form part of the commands). Is this possible please and how can I do this?
Thank you very much and regards,

Hi All!
I'm having an issue interacting between Matlab and .NET. I've managed to call .NET methods from Matlab code and vice versa. However, if I call a .NET method that, in turn, instantiates a Matlab object, it crashes (with a type initialization exception).
Think about this scenario: a .NET…

Hello,
when i tried to update some part of a matrix, i got the following error message:
??? Assignment has fewer non-singleton rhs dimensions than non-singleton subscripts
My code tries to update some values of a matrix that represent a binary image. My code is as follows:
outImage(3:5,2:4,1) =…

Hi, I am trying to find a very fast and efficient Fourier transform (FFT). Does anyone know of any good ones. I need to run it on the iPhone so it must not be intensive. Instead, maybe you know of one that is wavelet like, i need frequency resolution but only a narrow band (vocal audio range up…

Can somebody give a good explanation of FFT image transform
How the FFT transformed image and it's Re^2+Im^2 image can be analyzed?
I just want to understand something when loiking to the image and it's frequency.

Hi,
I am currently looking around for a good allround beat detection library / source code in C++ since I found it really hard to achieve satisfying results with the beat detection code I wrote myself using this tutorial:

It's…

So, I've been working on a little visualizer for sound files, just for fun. I basically wanted to imitate the "Scope" and "Ocean Mist" visualizers in Windows Media Player. Scope was easy enough, but I'm having problems with Ocean Mist. I'm pretty sure that it is some kind of frequency spectrum, but…

Trying to understand an fft (Fast Fourier Transform) routine I'm using (stealing)(recycling)
Input is an array of 512 data points which are a sample waveform.
Test data is generated into this array. fft transforms this array into frequency domain.
Trying to understand relationship between freq,…
