Unable to call my function and get an error

function h = fplothFUNC(d,Kp,A,t)
%the function is used to plot the following equation:
%     h*(t)=(d/Kp)*(1-exp(-(Kp/A)*t))
% call for function: 
%    h = fplothFUNC(1,[0.2 2 6 15 55 105],2,0:0.1:10)

LK=length(Kp);
Lt=length(t);
h=zeros(LK,Lt); %create a matrix of zeros for LK AND Lt columns
for i=1:LK    
    h(i,:)= (d/Kp(i))*(1-exp(-(Kp(i)/A)*t));
end

end

semilogy(t,h); xlabel('time (hours)'); ylabel('height difference (m)')

h = fplothFUNC(1,[0.2 2 6 15 55 105],2,0:0.1:10)

i get an error saying:

Error: File: fplothFUNC.m Line: 16 Column: 1
This statement is not inside any function.
 (It follows the END that terminates the definition of the function "fplothFUNC".)

d  = 1;
t  = 0:0.1:10;
Kp = [0.2 2 6 15 55 105];
A  = 2;
h  = fplothFUNC(d,Kp,A,t);
semilogy(t,h); xlabel('time (hours)'); ylabel('height difference (m)')

function h = fplothFUNC(d,Kp,A,t)
LK=length(Kp);
Lt=length(t);
h=zeros(LK,Lt); %create a matrix of zeros for LK AND Lt columns
for i=1:LK    
    h(i,:)= (d/Kp(i))*(1-exp(-(Kp(i)/A)*t));
end
end

thanks but why can it not be in this form?:

h = fplothFUNC(1,[0.2 2 6 15 55 105],2,0:0.1:10)

It can, I was just ordering the way I usually do.

The problem with your script was that the function was defined before the command calling it, and that is not how matlab works.

I hope this clarifies things. Please consider accepting the answer if it solved your issue, cheers!
