Output

Explanation of Program Code

clc;

It clears all input and output from the Command Window display giving clean screen. It removes items from workspace, freeing up system memory. After using clc, the scroll bar cannot be used to see the history of functions, but still the up arrow can be used to recall statements from the command history.

clear all;

It removes all variables from the workspace. This frees up system memory.

close all;

It deletes all figures whose handles are not hidden.

f=1000;

It stores the value 1000 in variable f.

t=0:1/(f*1000):2/f;

Here the following vector t is created.

Here this vector t is used as time axis(x axis) while plotting sinusoidal waveform.

y=sin(2*pi*f*t);

It is used to create sinusoidal waveform.

It multiplies each element of vector t with (2x 3.14x1000) and returns the circular sine of the elements of resulting vector.

Here f=1000. pi is always 3.14 approximately(constant).

That is why 2*pi*f*t = (2x 3.14x1000).

plot (t,y);

It plots all the lines defined by t versus y pairs.

xlabel ('Time');

It labels the x-axis as 'Time'. Each axes graphics object can have one label for the x-, y-, and z-axis. The label appears beneath its respective axis in a two-dimensional plot.

ylabel ('Amplitude');

It labels the y-axis as ' Amplitude. '

title ('Sinusoidal Waveform');

It outputs the phrase 'Sinusoidal Waveform' above the figure at the top.

grid on;

It adds major grid lines to the current axes.
