How do I stop getting extra zeros from a for loop?

Y=1.4
P3=113.15
vs_3=1.6884
c34= P3*(vs_3)^Y;
p34=zeros(size(1.69:+0.1:1.99));
for ve34= 1.69:+0.1:1.99
    i=i+1;
    p34(i)= c34./((ve34.^Y));
end

When running the for loop the p34 term retruns a 1x18 martix with mostly zeros with the intended restuls at the end. It should result in a 1x4 matrix with no zeros, but I keep getting these exra zeros. Does anyone know a way to fix this?

For some reason a different error "array indicies must be positive integers or logical values " occurs when run on 2022a compared to 2019a (what I have installed), which does not show that error when run on 2019a.
