Generate struct in dynamically Matlab, with different size fields

Question

I have a demand that is the following, I want to create a set of images and I will relate them, for that I create a struct vector similar to resultsInfo = struct('indice',0,'correlatas',cell(1,5),'fatorCorrelacao',zeros(1,5),'somaImagens',zeros(640,480));, where: Indice is an integer representing the image index; correlatas receives cell with 5 different image names that are similar factorCorrelation is a vector that receives a number that represents how similar these images are; and somaImages receive the sum of the 5 similar images.

When I do this, it fills the matrices of the somamage field, only of the first 5 elements of the vector, the rest it allocates an empty matrix. My intention is to dynamically fill the vector, because the number of images may vary according to each project.

Define the following method:

function resultStruct = CreateEmptySruct ()
    resultStruct.img_index = 0  ;
    resultStruct.correlated  = cell(1,5);
    resultStruct.correlationFactor = zeros(1,5);
    resultStruct.ImgSum = zeros(640,480) ;
end

Then call this method in For loop like this:

for i = 1 :5
    structArray(i) = CreateEmptySruct () ;
end

However you can also set any value separately for each struct, passing function arguments.
