[Image Analyst]

Try this:

rgbImage = imread('peppers.png');
[rows, columns, numberOfColorChannels] = size(rgbImage)

rows = 384

columns = 512

numberOfColorChannels = 3

startingRows = linspace(1, rows+1, 5)

startingRows = 1×5

1 97 193 289 385

for k = 1 : 4
    subplot(4, 1, k);
    row1 = startingRows(k);
    row2 = startingRows(k+1) - 1;
    imageStrip = rgbImage(row1 : row2, :, :);
    imshow(imageStrip)
    axis('on', 'image')
end
