How to express the sequence as a linear combination of unit step sequences?

How to express the sequence as a linear combination of delayed unit step sequences in MATLAB

Sequence: x[n] = {−4, 5, 1, −2, −3, 0, 2} , −3 ≤ n ≤ 3

[Torsten]

Can you give an example to clarify what you mean ?

Hi Tuce,

You can simply use the stairs function in MATLAB to express your sequence.

x = [-4, 5, 1, -2, -3, 0, 2]; 
n = -3:3; 

stairs(n,x) 

xlabel('n') 
ylabel('x[n], y[n]') 

You can also refer to the following documentation for your reference.
