how to write a plot for y=sinx in matlab

To plot a sine wave in Matlab, first generate a vector x that contains the values at which you want to evaluate the sine function, then calculate the corresponding values of y=sin(x) and plot them using the plot command.

Here's an example code snippet that shows how to plot a sine wave:

main.m
% Generate a vector of x values from 0 to 2*pi with a step size of 0.1
x = 0:0.1:2*pi;

% Calculate the corresponding values of y = sin(x)
y = sin(x);

% Plot the sine wave
plot(x, y);

% Add axis labels and a title
xlabel('x');
ylabel('y');
title('Sine Wave');

This code generates a vector x that contains values from 0 to 2pi with a step size of 0.1. It calculates the corresponding values of y=sin(x), and then plots them using the plot command. Finally, it adds axis labels and a title to the plot using the xlabel, ylabel, and title commands.
