Here is my code for --- Write a program to compute the circular convolution of two length-N

sequences via the DFT-based approach.

clc; clear all; close all;

x =[2+j3 3-1j -1+j2 j3 2+j4];

h =[-3-j2 1+j4 1+j2 5+j3 1+j2];

y = conv(x,h);

plot(x,h);

stem(x);

ylabel( 'AMPLITUDE');

xlabel('First Sequence');

subplot(3,1,2);stem(h);

ylabel( 'AMPLITUDE');xlabel('Second Sequence') ;

subplot(3,1,3);stem(y);

ylabel( 'AMPLITUDE');xlabe1('Output Sequence');

disp( 'The Resultant Signal is: ');y

Here i am getting error stating

Error in (line 3) x =[2+j3 3-1j -1+j2 j3 2+j4]

can someone help me as i am not sure if there somthing wrong this ''x =[2+j3 3-1j -1+j2 j3 2+j4''

I have been trying this sequnce with varies of other codes and method but still getting same error..

x = [2+3j 3-1j -1+2j 3j 2+4j];

Swap the number and j. So not j2, but 2j.
