Cretae a video from Images using WriterObj

I have 200 images, each one is an instantaneous frame captured each 0.1 sec. Therefore, I would like to create a video of 20 sec using all 200 frames. Anyone can help? Thanks and Regards.

I have already had a look at it and I generated the following codes:

close all; clear all; clc; tic; myFolder = 'C:\Users\Desktop\Test'; if ~isdir(myFolder) errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder); uiwait(warndlg(errorMessage)); return; end

% load the images images = cell(200,1); images{1} = imread('vector1.png'); images{2} = imread('vector2.png'); images{3} = imread('vector3.png'); images{4} = imread('vector4.png'); images{5} = imread('vector5.png');

but It does not work.
