How to overcome this error? Array formation and parentheses-style indexing with objects of class 'matlab.io​.datastore​.ImageData​store' is not allowed. Use objects of class 'matlab.io​.datastore​.ImageData​store' only as scalars or use a cell array.

i want to run a loop so that multiple images get convolve with different filters.As i shown below

for imageNum = 1:numImages for filterNum = 1:numFilters

    % convolution of image with feature matrix
    convolvedImage = zeros(convDim, convDim);

    % Obtain the feature (filterDim x filterDim) needed during the convolution

    convolvedImage=conv2( images(numImages), W(numFilters));
end
end

but i am getting an error "Array formation and parentheses-style indexing with objects of class 'matlab.io.datastore.ImageDatastore' is not allowed. Use objects of class 'matlab.io.datastore.ImageDatastore' only as scalars or use a cell array.

Error in contesting (line 48) convolvedImage=conv2( images(numImages), W(numFilters));" plz provide solution of it ?
