I am converting matlab to cpp with Matlab coder. I know that Mat object arrays aren't supported for matlab convertion and therefore I am getting error on the last line. Now, my question is how can I change the code to get pointsA and pointsB without causing issue on Matlab coder.

    function imgLocated = imageMatch(f1, vpts1, imgB, resizeAlign)
    originalB = imgB;
    imgB = imresize(imgB, resizeAlign);
    imgB = rgb2gray(imgB);
    imgB = histeq(imgB);
    points2 = detectFASTFeatures(imgB);
    [f2,vpts2] = extractFeatures(imgB,points2);
    indexPairs = matchFeatures(f1,f2);
    pointsA = vpts1(indexPairs(:,1)); pointsB = vpts2(indexPairs(:,2));
    
    if (pointsA.Count < 5 && pointsB.Count < 5)
        disp("Could not auto align, not enought number of features.");
        imgLocated = originalB;
        return;
    end
    
    [tform, ~, pointsAm] = estimateGeometricTransform(pointsB, pointsA, 'affine');
    tform.T(3,1) = (1/resizeAlign)*tform.T(3,1); tform.T(3,2) = (1/resizeAlign)*tform.T(3,2);
    %fprintf('Number of matches %d\n', pointsAm.Count);
    
    if (pointsAm.Count > 4)
        imgLocated = imwarp(originalB, tform, 'OutputView', imref2d(size(originalB)));
    else
        disp("Could not auto align, no enought matches.");
        imgLocated = originalB;
    end
    end
