Units in grating effect code

Hi, Hope every one is good.
So I am using matlab to predict the effects of a diffuser. I am using this code to input the diffusor and signal data:
v=343;
f=1000;
k=2*pi*f/v;
d=3;
N=12;
n=1:N;
height=[0,1,4,9,5,3,3,5,9,4,1,0,];
I am slightly confused as to units.
v = speed of sound (m)
f = frequency (Hz)
my issue is d = distance between wells (?) and the height of the wells (?) and what units are being used in the calculations. I am getting results but to accurately make assumptions i could do with knowing if matlab will be assuming cm or inch.
Any help appreciated,
Cheers

It's you should know what units you have. MATLAB operaes only with numbers, it doesn't care about units

Hi Dylan,
let's take a variable "d"(distance),
d=3000; %it is stored as double by default(No additional info about any units of d).
Assume a situation, the above distance is in meters according to you. if you want to work on kilometers as a unit, you have to assign in this way manually
d=3; %as 3000m = 3km, d is stored as double by default(No additional info about any units of d) you have to do it manually.
