About project

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:

: 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
