How can I do it ?

I am new in matlab

please help!!

I am using this coded but it shows vertical lines

stripeWidth = 2;
imageRows = 256;    % Whatever...
imageColumns = 256; % Whatever...
oneCycle = [128*ones(1, stripeWidth), zeros(1, stripeWidth)];
oneLine = repmat(oneCycle, [1, ceil(imageColumns/stripeWidth)]);
wholeImage = repmat(oneLine, [imageRows, 1]);
% Crop
wholeImage = wholeImage(1:imageRows, 1:imageColumns);
imshow(wholeImage);

stripeWidth = 2;
imageRows = 256;    % Whatever...
imageColumns = 256; % Whatever...

oneLine=ones(stripeWidth,imageColumns);
wholeImage=repmat( [oneLine;0*oneLine], imageRows/(2*stripeWidth),1);

imshow(wholeImage)

stripeWidth = 2;
imageRows = 256;    % Whatever...
imageColumns = 256; % Whatever...

wholeImage=true(imageRows,imageColumns);

for i=1:stripeWidth

    wholeImage(stripeWidth+i:2*stripeWidth:end,:)=0;
    
end

imshow(wholeImage)

stripeWidth = 2;
imageRows = 256;    % Whatever...
imageColumns = 256; % Whatever...

wholeImage=true(imageRows/stripeWidth,imageColumns);
wholeImage(2:2:end)=0;
wholeImage=repelem(wholeImage,stripeWidth,1);

imshow(wholeImage)
