[Solved] What will be the output of the following MATLAB code?t = 0:0.1:1;plot(t, t);hold on;plot(t, t.^2); — Ans: Two plots will appear: a straight line and a curve on the same figure. | MATLAB

MATLAB - 2D Plotting

What will be the output of the following MATLAB code?

t = 0:0.1:1;
plot(t, t);
hold on;
plot(t, t.^2);

ATwo plots will appear: a straight line and a curve on the same figure.

BOnly the plot of t vs t^2 will be shown.

CAn error will occur because hold on is used incorrectly.

DOnly the plot of t vs t will be shown.

Step-by-Step Solution

Solution:

Step 1: Analyze the first plot command
The first plot draws a straight line y = t on the figure.
Step 2: Understand the effect of hold on and second plot
Using hold on keeps the first plot visible, so the second plot y = t^2 is drawn on the same figure as a curve.
Final Answer:
Two plots will appear: a straight line and a curve on the same figure. -> Option A
Quick Check:
hold on keeps previous plot, so both appear [OK]

Quick Trick: hold on keeps old plots visible for new ones [OK]
