Trouble with Matlab Embedded Function Coding
Hi, I am trying to use embedded function block to incorporate m-file code that will manipulate data at every simulink simulation time step. When I try to run the simulation I get the following error message: Subscripting into an mxArray is not supported. Function 'Embedded MATLAB Function' (#18.1137.1148), line ... 27 Jan 2010 14:53

phase in FFT
I am new to Fast Fourier Transform and have a general question regarding the phase information. I understand for the real-valued data, the FFT is symmetrical. What is the phase relation between the positive and negative frequency domain? In Matlab, the two phases seem to have the same value with opposite signs. Is this... 19 Jan 2010 19:11

Repetitions, starting ending index and repeated value
Dear All, I'm looking for a FEX submission that finds blocks of repeated numeric values (including NaN) and returns the starting and the ending index/indexes, the lenght/lengths of the repeated block/blocks, the number of blocks and the value itself . Example: In = [1,2,3,3,3,NaN,NaN,3,3,3,3,4,5,6,7]; Out(1).V... 19 Jan 2010 12:22
