MATLAB: How we can declare and initialize matrix of different name of same size in for loop

Question

for i=1:5
vector+num2str(i)=zero(i:4);
end

Answer 1

Try this:

featureMatrix = zeros(numFeatures, numImages);
for k = 1 : numImages
    % Analyze each image.....
    thisFeatures = AnalyzeSingleImage(thisFilename);
    % Put feature vector into column k.
    % All feature vectors should have the same number of measurements.
    featureMatrix(:, k) = thisFeatures;
end

Another option is you could use a structure array instead of a simple 2-D numerical matrix.
