How does this code solve the problem of incorrectly using vertcat to concatenate arrays with inconsistent dimensions?

On the line that throws the error you have:
y=[o3*180/pi;
04*180/pi];
where o3 is of size 1x3601 and 04 is a scalar (the scalar number 4). I suspect you meant to use o4, which is the same size as o3.
y=[o3*180/pi;
o4*180/pi];
