I created an added variable plot for a whole model, based on 4 predictor variables. I don't understand the values that are now on the x-axis: "adjusted whole model." Where are thes…
Hi all, I have a timeseries vector lets say with 7 points : v=[0.18 3.15 0.18 0.16 0.17 0.58 0.33 ]; I would like to create a new vector by interpolating data so I have extra…
I am running a for loop on 10 million lines of data and it has taken over a day and is still running. I have preallocated the array I am modifying according to suggestions provided…
Hello, I want to solve the following equation: 1/c0 c^2 - c +X*t / c0 = 0 where c0 is a given constant but X and t are constant arrays: they are data sets where X varies w…
Hello, I'm very new to DSP concepts and signal processing in MATLAB so please go easy on me. I have the following code that I've begun working on which is the BZT of an RLC fi…
Just a quick question - are 'filter coefficients' the coefficients of the impulse response, desired transfer function, or actual transfer function? …
Dear Community, I would like to print a sinewave with volume automation in mathlab. I am already able to print a stereo wave file with a fixed amplitude. Is it possible to set t…
fs = 512; X = [-2 1 -3 5 -1 3 -4 4 -2]; lX = length(X)-1; Y = -diff(X)/2.*cos(pi*(0:1/fs:1-1/fs)') + (X(1:lX)+X(2:lX+1))/2; % Y = [Y(:);X(end)]; plot(0:lX,X,'o',0:1/fs:lX,Y) …
