About project

2. My project consist of different
function :
1:) To Generate A Matrix
2:) To Represent The Harmonics of a Signal
3:) To represent unit impusle
4:) To represent the descrete unit step
function graph of a signal
5:) To represent the continous unit step
function graph of a signal
6:) To represent the ramp function graph of
a signal
7:) To find the convolution of the signal
8:) To find the graph of cosin function
9:) To find the graph of sin function
Application:

3. : it make easy to graph different function
:it have a function to get random matrix as
will as ones matrix
:it have also a function of harmonic signal
:it have also function of flipping
:it have also function of ramp function
:it have also unit impuls and unit step
function
We see that all the above function have
very use in daily life .so our project is on
the base of all above mentioned function

4. Function coding:
function y=pro()
disp('"0" To Generate A Matrix ')
disp('"1" To Represent The Harmonics of a Signal ')
disp('"2" To represent unit impusle of a signal ')
disp('"3" To represent the descrete unit step function graph of a signal ')
disp('"4" To represent the continous unit step function graph of a signal ')
disp('"5" To represent the ramp function graph of a signal ')
disp('"6" To find the convolution of the signal')
disp('"7" To find the graph of cosin function ')
disp('"8" To find the graph of sin function ')
