MATLAB How to plot a continuous zero plot in Matlab?

[hokhani]

In the plot command below

x=1:5:100
plot(x,y,x,0)

one plot is noncontinuous zero plot. How can I plot a continuous zero one?

 

[Dr Transport]

define y1 = zeros([1 500]); and plot it...

Try

x = 1:5:100;
plot(x, zeros(size(x));

(Same thing as Dr Transport suggested, except it makes sure the vector of zeros has the same size as x.)
