drawframe(1);
Write your drawframe function below
function drawframe(n)
% Define the characters to use
chars = char(['A':'Z' 'a':'z' '0':'9' '!@#$%^&*()-_=+[{]}\|;:''",<.>/?']);
% Define the size of the plot
width = 48;
height = 20;
% Define the number of text objects to plot
numText = 100;
% Create a matrix of random x coordinates and characters
x = randi([1, width], numText, 1);
charIndex = randi(numel(chars), numText, 1);
% Create a vector of y coordinates that shifts with each frame
y = mod((1:numText)' + n, height);
% Create the plot
clf;
hold on;
set(gcf, 'Color', 'k'); % set the figure color to black
set(gca, 'Color', 'k', 'YDir', 'reverse');
axis off;
axis([1, width, 1, height]);
% Plot the text objects
for i = 1:numText
text(x(i), y(i), chars(charIndex(i)), 'Color', 'g');
end
hold off;
end
