Generate the Complex exponential sequence with MATLAB

Code:

clc;

clear all;

a=input('Type in real exponent : ');

b=input('Type in complex exponent : ');

c=a+b*i;

k=input('Type in the gain constant : ');

N=input('Type in length of sequence : ');

n=1:N;

x=k*exp(c*n);

subplot(2,1,1)

stem(n-1,real(x));

xlabel('time index n');ylabel('amplitude');

title('real part');

subplot(2,1,2)

stem(n-1,imag(x));

xlabel('time index n');ylabel('amplitude');

title('imaginary part');

ourput:

Type in real exponent : -1/12

Type in complex exponent : pi/6

Type in the gain constant : 4

Type in length of sequence : 40
