[Solved] What will be the visible effect of running this MATLAB code?figure; axis([0 10 0 100]); for x = 1:10 y = x^2; plot(x, y, 'ro'); drawnow; pause(0.3); end | MATLAB

MATLAB - 3D Plotting and Visualization

What will be the visible effect of running this MATLAB code?

figure;
axis([0 10 0 100]);
for x = 1:10
    y = x^2;
    plot(x, y, 'ro');
    drawnow;
    pause(0.3);
end

AOnly the last red dot at (10,100) is visible

BAll red dots appear at once after the loop finishes

CThe plot window stays blank with no dots

DRed dots appear one by one at points (1,1), (2,4), ..., (10,100)

Step-by-Step Solution

Solution:

Step 1: Understand the loop plotting behavior
Each iteration plots a red circle at (x, x^2) and calls drawnow to update the figure immediately.
Step 2: Effect of axis limits and pause
Axis limits prevent resizing, and pause(0.3) delays so dots appear one by one.
Final Answer:
Red dots appear one by one at points (1,1), (2,4), ..., (10,100) -> Option D
Quick Check:
drawnow + pause shows points sequentially [OK]

Quick Trick: drawnow + pause shows animation step-by-step [OK]
