Hey there! Let's break down exactly what you need — both a targeted solution for your matrix visualization scenario, and a general method to schedule a screen clear after 60 seconds.

1. Targeted Solution: Visualize a Random Matrix, Then Auto-Clear After 1 Minute #

If you want to generate a random matrix, show it (either in the command window or as a plot), and have the screen cleared without pausing your workflow, MATLAB's timer object is perfect for this. Here's a complete set of commands you can run:

% Step 1: Generate and display your random matrix
random_matrix = rand(8); % 8x8 random matrix — adjust the size to fit your needs
disp('Generated Random Matrix:');
disp(random_matrix);

% Optional: Add a visualization (like a heatmap)
imagesc(random_matrix);
colorbar;
title('Random Matrix Heatmap');

% Step 2: Set up timer to clear screen after 60 seconds
clear_timer = timer(...
    'StartDelay', 60, ...
    'TimerFcn', @(obj, ~) (clc; close(gcf); delete(obj)), ...
    'ExecutionMode', 'singleShot' ...
);
start(clear_timer);

Let me explain the timer part:

• StartDelay, 60: Makes the timer wait exactly 1 minute before running its task.
• TimerFcn: This is what runs when the timer triggers — clc clears the command window, close(gcf) closes the visualization figure, and delete(obj) cleans up the timer so it doesn't linger in memory.
• ExecutionMode, 'singleShot': Ensures the timer only runs once (no repeated clearing).

If you don't need the plot visualization, just simplify the TimerFcn to @(obj, ~) (clc; delete(obj)).

2. General Method to Schedule a Screen Clear After 1 Minute #

For any scenario where you want to auto-clear the screen after 60 seconds (regardless of what you're working on), the timer approach is still the best choice because it runs in the background — you can keep coding or running commands while waiting. Here's the core code:

% Create a one-time timer to clear the command window
general_clear_timer = timer(...
    'StartDelay', 60, ...
    'TimerFcn', @(~, ~) clc, ...
    'ExecutionMode', 'singleShot' ...
);
start(general_clear_timer);

If you also want to close all open figure windows along with the command line, update the TimerFcn to:

@(~, ~) (clc; close all)

There's also a simpler but blocking alternative if you don't mind pausing your MATLAB session for 1 minute (you can't do anything else until the time is up):

pause(60); % Wait 60 seconds
clc; % Clear command window
% Add close all; here if you want to shut down all figures too

But the timer method is way more flexible for ongoing work!
