File name 'VanDeemter.m'. This function can calculate
the theoretical plate height of a chromatographic column
at different mobile phase velocities according
to the Van Deemter equation. Furthermore, the optimal
mobile phase linear velocity can be determined.

Seven input values : 'dp', 'D', 'dc', 'epsilon', 'A', 'B' and 'C'
Three output values : 'H', 'u' and 'u_opt'

INPUT
epsilon : volume fraction
dc : column diameter (m)
dp : particle size (m)
D : diffusion coefficient (m2/s)
A : A-term of the Van Deemter equation
B : B-term of the Van Deemter equation
C : C-term of the Van Deemter equation

OUTPUT
H : theoretical plate height (micrometer)
Hmin : minimal value of plate height (micrometer)
u : mobile phase linear velocity (cm/min)
u_opt : optimal mobile phase linear velocity (cm/min)


Input syntax : [H, Hmin, u, u_opt] = VanDeemter(dp,D,dc,epsilon,A,B,C)
