Store a values in to a table at each iteration of loop

Create a table to store the computed values with each itreation of a loop.

With reference to the given code, I want to store the labeled values of f1,f2,f3 in to a table with each iteration of loop

clear all

close all

v1=[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1];

Fs=12000; %sampling frequency

T=1/Fs; %sampling period

L=length(v1); %Lenght of the signal

t=((0:L-1)*T)';

requiredLength=5;

requiredArray3 = [];

frequencyArray = [];

freq = ((1:5)*Fs/5);

%loop

for n = v1

requiredArray3 = [requiredArray3, n];

if numel(requiredArray3) == requiredLength

fastFourier = fft(requiredArray3);

A = fastFourier(:,1:3);

B = freq(:,1:3);

f1 = sum(B.*A)/sum(A);

f2 = sum(requiredLength - f1)/requiredLength;

f3 = sum(sqrt(B-f1).*A)/requiredLength.*sqrt(f2);

requiredArray3 = [];

end

end

Vaibhav, I want to store the values in table for each itteration of loop? So as per the code I got the data into the three rows because I consider the length of array 5 out of 15 for each iteration.

If you want to store every 5 element, then use

f1 = f1(1:4:end)
