How to stop popping up of plot figures unnecessarily in Matlab app designer?

function [array, array_C, param] = outline_BF(microwells, fudgefactor)
% Program for creating outline on 3D structrues
param = zeros(25,6); array = cell(25,1); array_C = cell(25,1);
for b = 1:25
    
% Outline for bright field..................................................
    image = microwells{b};
    [~,threshold] = edge(image,'Sobel');
    BWO = imbinarize(imadjust(image), threshold*fudgefactor); 
    BW = imcomplement(BWO);
    seD = strel('diamond',9); 
    BW3 = imdilate(BW,seD); 
    BW4 = imfill(BW3,'holes');
    BWM = imerode(BW4,seD); % addition new
    BW5 = imerode(BWM,ones(17));
    BW6 = imdilate(BW5,ones(17));
    BWoutline = bwperim(BW6, 8);
    temp = imoverlay(image,BWoutline,'cyan');
    bound = []; boundary = []; intensity = [];
    [bound,I,~,~] = bwboundaries(BW6,'noholes');
    %figure,imshow(image)
    bound_S = rem_edge(I);
    A = 0; 
    black = logical(zeros(size(BW6))); 
  
    if ~isempty(bound_S)
        for k=1:length(bound_S)
            boundary = bound{bound_S(k)};
            Par = blob_parameters(boundary(:,2), boundary(:,1));
%             labeledImage = logical(BW6);
            if Par(1) > A
                param(b,1:5) = Par;
                plot(boundary(:,2), boundary(:,1),'r-', 'LineWidth', 1);     % plot boundaries
                A = Par(1);
                BW7 = select_bound(black, boundary);
                BW7f = imfill(BW7,'holes');
                intensity = regionprops(BW7f, image, 'MeanIntensity');
                param(b,6) = intensity.MeanIntensity;
            end
        end
    else
        param(b,:) = [NaN NaN NaN NaN NaN NaN];
        BW7f = BW6;
    end
    
    BWoutline2 = bwperim(BW7f);
    array{b} = imoverlay(temp,BWoutline2,'red');
    
 % Canny for bright field...................................................
    array_C{b} = edge(image, 'Canny');
end

This worked,

 figure('Visible', 'off'); % I put this before and it worked 
 
 BWoutline = bwperim(BW6, 8);

There is no need to draw the plot if you are not using it. Unless you want to save the figure without displaying it. Could speed up your program by commenting it out.
