Function with duplicate name "aAcou1" cannot be defined.

% this function calculates and plots the sound pressure of a single source 
c= 343;
function [spl] = aAcou1(f,P,t) 
 if  f == 40 
     A1 = 10 ;
     A2 = 10;
     w = 2*pi*f;
     k = w/c;
 end 
x = [1:h:12];
y = [1:h:15];
[yy,xx]= meshgrid(y,x);
H1 = sqrt((xx-0).^2+(yy-9).^2);
H2 = sqrt((xx-9).^2+(yy-16).^2);
Lx = length(x);
Ly = length(y);
phase = zeros(Lx,Ly);
phase2 = zeros(Lx,LY);
Meanpressure = zeros(Lx,Ly);
spl = zeros(Lx,Ly);
 
for a = 1:Lx
    for b = 1:Ly
      phase(a,b)=  ((A1+P)./H1(a,b))*exp(1j*((w*t)-(k*H1(a,b))));
      phase2(a,b)= ((A2+P)./H2(a,b))*exp(1j*((w*t)-(k*H2(a,b))));
    end 
end
  phase3= phasor+phase2;
 for a = 1:Lx
    for b = 1:Ly
      Meanpressure(a,b) = sqrt(0.5*phase3(a,b)*conj(phase3(a,b)));
      spl(a,b)= 20*log10(Meanpressure(a,b)/(20*10^(-6))); 
    end 
 end
     figure 
 surf(X,Y,spl)
end
 

I am confused why I get the error Function with duplicate name "aAcou1" cannot be defined. I have save it as the same name and only have one file of aAcou1 ,confused lol.

Save the code in a separate file named as aAcou1.m , define c inside the function. Why so obssessed with that name ?? Why if you change the name to aAcoU the earth won't spin or what?

which aAcou1 -all % to see if any other file exists with the same name
