Hiee I am new to matlab help me out solving this error in my program:

This is my program:

clc;
close all;
clear all;
x= [0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0];

%--Polar NRZ--%

y=2.*x-1;

figure

stairs(1:length(y),y)

for j=1:G        
    PN1=[PN1 sd1(5)];
    if sd1(1)==sd1(4)
        temp1=0;
    else temp1=1;
    end
    sd1(1)=sd1(2);
    sd1(2)=sd1(3);
    sd1(3)=sd1(4);
    sd1(4)=sd1(5);
    sd1(5)=temp1;
end

The error is here:

o= s1*z;

where you are trying to multiply ‘s1’, a (1x1000001) double by ‘z’, a (1x63) logical.

What do you want to do?
