Error: Not enough input argument (line 6)

function L = QoS(Data,model,estR,estE)

load('HMMParam.mat');
S = xlsread('Dataset.xlsx');

model = model(1:size(Data,1));
model = model/max(model(:));
model = round(model);
R = logical(model);

T = Data(R,:);

G = zeros(sum(R),1);

for i = 1:sum(R)
    
    Q = T(i,:);    
    Co = hmmdecode(Q,estR,estE);
    Q = Q.*Co;
    G(i) = sum(Q);
    
end

L = 1 - mean(G);

end

Pass the inputs to the function Data,model,estR,estE.

1. Save the function file in same directory
2. Call the function from different m script

%Define all parameters
Data=
model=
estR=
estE=
y=QoS(Data,model,estR,estE)

Read about custom function call here

or if you want to run function from editor, look at here
