Hello, My purpose is to plot a figure of the frames of a video stored in an array named 'processo' as you can see in the code below:

if true
folder = fileparts(which('Field_adv_diff_2D.avi'));
movieFullFileName = fullfile(folder,'Field_adv_diff_2D.avi');
videoObject = VideoReader(movieFullFileName);
numberOfFrames = videoObject.NumberOfFrames;
for frame = 1:numberOfFrames
thisFrame = read(videoObject,frame);
if frame == 1
  h = size(thisFrame,1);
  w = size(thisFrame,2);
  processo = zeros(h, w, 3, numberOfFrames);
end
processo(:, :, :,frame) = im2double(thisFrame);
end
end

The video is a simulation of a diffusive process in grey scale. I need to plot its frame in every iteration of a for loop but with the following code I didn't get the hoped results

    if true
  figure
  plot(processo(:,:,1,i));
    end

Might anyone help me?

Thanks in advance Davide

Hello, what are the results you observe, and what is the expectation?
