Open in MATLAB Online Are you sure the column imported was all numerical data? Can't say anything more without seeing the Excel file (you can upload using the paperclip icon). Or load the data from the Excel file and type >> whos varname ...
I have to find the frequency of the input, so I wrote some code in Matlab function (by the http://www.mathworks.com/help/techdoc/ref/fft.html) : { function [freq, amp] = fcn(u) %#codegen Fs=2000; T=1/Fs; L=length(u); ...
Plot the phase as a function of frequency. Get tol = 1e-6; z(abs(z) < tol) = 0; theta = angle(z); stem(f,theta/pi) title("Phase Spectrum of x(t)") xlabel("Frequency (Hz)") ylabel("Phase/\pi") grid Interpolation of FFT Copy Code Copy Command Interpolate the Fourier ...
This section of code should loop through the table of data in the column I tell it to, and if it is not 0 or blank it should copy the whole row of the table to another spreadsheet which is my formatte... Angular function being called multiple times ...
Open in MATLAB Online Ran in: test.csv Add: xlim([0 1.5E+3]) after theplotcall to distinctly see the two peaks. Tweaked code — % Read the CSV file, automatically skipping the header row data = readmatrix('test.csv'); % Extract the time and data columns ...
Using extrapolation to suppress edge effects FFT derivatives of multi-dimensional data clear; closeall; clc; Syntax [dY,fft_dY]=FFT_derivative(dt,Y,dimDer,derOrder,numPad); Description This function uses the Fourier transform method to compute the derivative of orderderOrderfor the input dataY,...
You cannot calculate the Fourier transfomors without a corresponding sampling frequency or time vector.
