Why does "insufficient input arguments" appear? Obviously, all the variables that go into the formula are specified.

function C= gaussian_plume(C,S,pi,u,sigmay,sigmaz,y,z,H,a,b,c,d,f,dx,dy,dz,i,j,k,p,L);

dx=1;

dy=1;

dz=1;

S=10000;

u=10;

H=100;

L=50; % dx,dy,dz,S,u,H,L

for i=-500:100:500;

x=i*dx;

for j= -500:100:500;

y=j*dy;

for k= 0:100:1000;

z=k*dz; % x,y,z

if(x<=1000);

a=213;,b=0.894;,c=440.80;,d=2.904;,f=9.27;,pi=3.141592; %a,b,c,d,f,pi

sigmay=a*(x^b);

sigmaz=(c*(x^d)+f);

J=(exp((-(z-H+2*p*L)^2)/2*sigmaz^2)+exp(-((z+H+2*p*L)^2)/2*sigmaz^2)); %"Not enough arguments" error occur

C=(S/(2*pi*u*sigmay*sigmaz))*exp(-y^2/2*sigmay^2)*(symsum((J),p,-inf,inf));

fprintf('%f %f %f %.15f\n',x,y,z,C);

elseif(x>1000);

a=213;,b=0.894;,c=459.7;,d=2.904;,f=-9.6;,pi=3.141592;

sigmay=a*(x^b);

sigmaz=(c*(x^d)+f);

J=(exp((-(z-H+2*p*L)^2)/2*sigmaz^2)+exp(-((z+H+2*p*L)^2)/2*sigmaz^2)); %"Not enough arguments" error occur

C=(S/(2*pi*u*sigmay*sigmaz))*exp(-y^2/2*sigmay^2)*(symsum((J),p,-inf,inf));

fprintf('%f %f %f %.15f\n',x,y,z,C);

end

end

Hi,

You haven't called the function, you just ran the function. You need to call the function with all the required arguments after defining the function.

[Walter Roberson]

However the error message is about gaussian_plume2 and we are shown gaussian_plume without the 2.

I suspect that you are correct about the cause, but we can't quite prove it.
