How to increase elements of a vector without changing its plot?

Hello forum, I have a vector of x elements (57x1) that I would expand to a y-size vector (3000, for example) but without changing its plot (it is a particular stairs plot). Any idea on how to do it?

If you have
X = rand(57,1); %57 elements
if you want to have 3000 elements now,
X(end+1:end+3000,1) = rand(3000,1);
if you only want to plot the first 57 elements,
plot(X(1:57,1))

I'm not clear with what do you mean. Please show me how you create these vectors.
If you want to create more number of elements between the same limits, use linspace.
x_57 = linspace(1,30,57);
x_3000 = linspace(1,30,3000);
if you want to "append" more elements to the first vector ( x_57), then
x_57_new = [x_57 newVector]
