Unrecognized function or variable 'gaussian_plume_model'

Hi, I have this script and I´m stuck with this problem:

M_Coal = 5000

Cal_Value = 3000

S_Content = 20

h = 100

d_flue = 5

n_flues = 1

a_flues = n_flues*pi*(d_flue/2)^2;

d = sqrt(n_flues)*d_flue;

S_AM = 32

SO2_MW = 63

Q = 10

FGD_Eff = 70

Q_FGD = Q*(100-FGD_Eff)/100;

GVperGJ = 5000

FGV = 5000

Vs = FGV/24/3600/pi/(d/2)^2;

U = 10

Ts = 180

Ta = 25

a = 0.3658

p = 0.9031

b = 0.00025

q = 2.125

dh = 30

H = 30

vx = U*(H/h)^0.143;

x_range = [0:200:100000];

y_range = [-20000:200:20000];

par = [Q_FGD,vx,H,a,p,b,q];

Surf_Conc = gaussian_plume_model(x_range,y_range,par);

Unrecognized function or variable 'gaussian_plume_model'.

Are any package or anything else that I have to add to my scrip to allow it to read the function 'gaussian_plume_model' or how can I call the fuction?

gaussian_plume_model is a function which needs to be in same folder where you are running your script file. Try running your script with function file in same folder.

You don't need to install other packages
