My Prof. give me a code which include something like "signal(...)" but it causes error in my computer. we compared our doc.s and saw that we have same "signal.m" with same content.…
How can I change dspdata spectrum units, its in dB (dB/Hz for PSD), I would like the spectrum in real units. …
Hi, I used the butterworth filter with the [b,a] syntax: filtord=4; SampleRate=20000; d = fdesign.bandpass('N,F3dB1,F3dB2',4,100, 300,SampleRate); hd = design(d,'butter'); % …
How can I find the value of vector for the local maximum and the nearest local minima (befor and after maximum value)? I have a vector array (e.g. 2 12 4 6 9 4 2 5 10 19 7 5 3 7 …
I want to know if I can use filter objects for GPUs in MATLAB 8.1 (R2013a). I have the Jacket from AccelerEyes but their filter performance is slower than the MATLAB filter perfo…
Hi, I am trying to simulate the signal by Embedded matlab function in sumulink. The function has two input T=10e-6,B=30e6 and one output. The code as below function y = chir…
[P,F] = spectrum(SSSS,128,0,hanning(128),1/15); is the old version of matlabs solution to find the spectrum of the signal named 'SSSS'. can any one explain this ?? what is the eq…
I have a vector such as A = [1 2 2 3 2 4 5 7 6 6 5 4]. As we can see that 7 is the maximum value of this vector. I want to know the location of this maximum value, in this example …
