MATLAB: How to use the “parse” function to create optional function inputs

MATLABparse

Hello,
I am trying to use "parse" to create optional function inputs. Tried to replicate examples in the documentation (see below and attached) but I get the "too many arguments" error. Any idea? Thanks
my code below:
—————-
function []=testFun(A,varargList)
p = inputParser;
defaultNorm = 'L2';
validNorms = {'L1','L2'};
checkNorm = @(x) any(validatestring(x,validNorms));
addOptional(p,'lambda',0,@isnumeric)
addOptional(p,'norm',defaultNorm,checkNorm)
parse(A,varargList{:})
lambda = p.Results.lambda;
norm = p.Results.norm;
disp('input1 = ')
disp(A)
disp('lambda = ')
disp(lambda)
disp('norm = ')
disp (norm)
end

Hello,
I changed the name to varargin, but it still doesn't work, I have an error on the "parse" line. What am I missing?
See code below.
Thanks for your help.

function []=testFun(A,varargin)
p = inputParser;
defaultNorm = 'L2';
validNorms = {'L1','L2'};
checkNorm = @(x) any(validatestring(x,validNorms));
addOptional(p,'lambda',0,@isnumeric)
addOptional(p,'norm',defaultNorm,checkNorm)
parse(A,varargin{:})
lambda = p.Results.lambda;
norm = p.Results.norm;
disp('input1 = ')
disp(A)
disp('lambda = ')
disp(lambda)
disp('norm = ')
disp (norm)
end
