Sine Wave Generator

This script generates a sine wave based on user-defined frequency and amplitude.

%clear work space and command window
clear;clc;

%user input for frequency and amplitude
frequency=input('Enter the frequency of the sine wave (Hz): ');
amplitude=input('Enter the amplitude of the sine wave: ');

%time vector from 0 to 1 second with a sampling rate of 1000Hz
t=0:0.001:1;

%Generate the sine wave
y=amplitude*sin(2*pi*frequency*t);

%plotting the sine wave
