How to draw a helix knowing the pith, diameter and height ?

Hi all

the following code creates a helix, but not in the range I want. Is there a function that gets the dia, pitch and height and make the helix ?

syms t
xt = sin(t);
yt = cos(t);
zt = t;
fplot3(xt,yt,zt)

You can create it using these formulas.

dia = 2;
pitch = 0.1;
height = 1;

syms t
radius = dia/2;
x = radius*sin(t);
y = radius*cos(t);
z = t/(2*pi)*pitch;
tmax = 2*pi*height/pitch;

fplot3(x, y, z, [0 tmax], 'LineWidth', 2)

what is the purpose of syms and and why did u divede the t with 2*pi at z
