Goodmorning somebody there, I want to read in images of different dimensions into an array but am having this error

Error in ==> loadExample at 10
    myArray(:,:,:,p) = imread(fullfile(H, myFile{p}));

my code is as below:

H = fullfile('C:\Users','Adigun','My Documents','One_Thousand'); 
myFolder = dir(fullfile(H,'0*.jpg'));
myFile = {myFolder.name};
numImage = numel(myFile);
I = imread(fullfile(H, myFile{1}));
%figure(7), imshow(I);
myArray = zeros([size(I) numImage], class(I));
%myarray(:,:,1) = I;
for p = 1:numImage
    myArray(:,:,:,p) = imread(fullfile(H, myFile{p}));
end
figure(8), imshow(myArray(:,:,:,2));

try this is code:

myArray = cell(1,numImage); 
for p = 1:numImage
    myArray{p} = imread(fullfile(H, myFile{p}));
end
