how to over come vector mismatch error in plot

tp=2.2676*10^-3;
Ts=22.6757*10^-6;
n=0:Ts:100;
fp=(1/tp);
w=2*pi*fp;
p=sin(w*n*Ts);
p(find(p<0))=0;
data = randi([0,1],1,100);
a=[];
for k=1:2:100
    if data(k)==0 && data(k+1)==0
        a=[a 1];
    elseif data(k)==0 && data(k+1)==1
        a=[a i];
    elseif data(k)==1 && data(k+1)==0
        a=[a -1];
    elseif data(k)==1 && data(k+1)==1 
        a=[a -i];
    end
    
end
y_s=conv(a,p);
plot(n,y_s);
vector mismatch between n and y_s

You can try :

tp=2.2676*10^-3;
Ts=22.6757*10^-6;
n=0:Ts:100;
fp=(1/tp);
w=2*pi*fp;
p=sin(w*n*Ts);
p(find(p<0))=0;
data = randi([0,1],1,100);
a=[];
for k=1:2:100
    if data(k)==0 && data(k+1)==0
        a=[a 1];
    elseif data(k)==0 && data(k+1)==1
        a=[a i];
    elseif data(k)==1 && data(k+1)==0
        a=[a -1];
    elseif data(k)==1 && data(k+1)==1 
        a=[a -i];
    end
    
end
y_s=conv(p,a,'same');
plot(n,y_s);

I hope this is what you want, let me know if you have doubts !

Side Note : Did you really mean to add 'i' (imaginary number) to the 'a' vector or you meant to add 'k' (for loop's variable)?

No, but thank you got the answer we just need to plot using different vector.
