How to set tics in x or y axis using range in GNU Octave?

问题

length of x = 1000, length of y = 1000

plot(x, y, '+');
xlabel ("p");
ylabel ("Q(p)");
title('Custom plot');
set(gca, 'xtick', [0.00000   0.20000   0.40000   0.60000   0.80000   1.00000])

This set command creates 6 tics in X axis, but I like to create 20 ticks so that there are 50 elements in between 2 tics.

Thanks in advance.

From your comment I guess you don't know the concept behind Octaves "range". see here

In your case if you want the xticks go from 0 to 1000 and the difference between the steps is 20 just use:

set(gca, 'xtick', 0:20:1000);
