How to plot two figures side by side in a same plot?

I am using subplot command to plot two figures side by side in a same plot but both figures are not appearing. Please help me to detect error in my code. Below is my code.

clear all; close all; clc;

Use either of subplot() or tiledlayout().

Not both of them together.

[Adam Danz]

tiledlayout and subplot do not work together. They each offer a means of adding multiple axes to a figure. Tiledlayout is the more modern approach and is recommended over subplot.

The code below makes the following changes from your original code

• Removes subplot
• Replaces tiledlayout('flow') with tiledlayout(1,2) assuming you want a 1x2 grid of axes.

See the 5 changes I made, indicated by arrows in the comments.

The subplot and tiledlayout calls appear to be interfering with each other.

Commenting-out the tiledlayout calls produces this —
