[Solved] Consider this MATLAB code:t = 0:0.2:1;plot(t, sin(2*pi*t));hold on;plot(t, cos(2*pi*t));hold off;plot(t, t);What will be displayed in the figure window? | MATLAB

MATLAB - 2D Plotting

Consider this MATLAB code:

t = 0:0.2:1;
plot(t, sin(2*pi*t));
hold on;
plot(t, cos(2*pi*t));
hold off;
plot(t, t);

What will be displayed in the figure window?

AOnly the sin and cos plots are visible, line plot erased.

BOnly the line plot of t vs t is visible.

CAll three plots (sin, cos, and line) are visible together.

DAn error occurs due to <code>hold off</code> usage.

Step-by-Step Solution

Solution:

Step 1: Plot sin and cos with hold on
The first two plots (sin and cos) appear together because of hold on.
Step 2: hold off disables hold, so next plot replaces all previous plots
After hold off, the last plot(t, t) clears the figure and shows only the line plot.
Final Answer:
Only the line plot of t vs t is visible. -> Option B
Quick Check:
hold off clears previous plots = C [OK]

Quick Trick: Use hold off to reset plot before new plot [OK]
