how to save each loop variable in the same vector?

hello, every one i have question

i make a loop code to get vi, fi

but, i want to save this vi fi data in the same vector

please let me know how to save result of vi and fi in same vector,

thank you,

%data set = x 
n = 24;
for i = 1:numel(x)-n+1
    xi = x(i:i+23);
envelope(xi,1,'peak') 
[peakHeights,valleyHeights] = envelope(xi,1,'peak') 
vi = sum(peakHeights-valleyHeights);
[peakHeights, indexesOfPeaks] = findpeaks (xi); 
[valleyHeights, indexesOfValleys] = findpeaks (xi); 
fi = [numel(indexesOfPeaks) + numel(indexesOfValleys)]
end

%data set = x 
n = 24;
M = numel(x)-n+1;
all_vi = zeros(1,M);
all_fi = zeros(1,M);
for i = 1:M
    xi = x(i:i+23);
    envelope(xi,1,'peak');
    [peakHeights,valleyHeights] = envelope(xi,1,'peak'); 
    vi = sum(peakHeights-valleyHeights);
    [peakHeights, indexesOfPeaks] = findpeaks (xi); 
    [valleyHeights, indexesOfValleys] = findpeaks (xi); 
    fi = numel(indexesOfPeaks) + numel(indexesOfValleys);
    all_vi(i) = vi;
    all_fi(i) = fi;
end

thank you very much! it works!
