why is my code not working for a particular set of input?

3 views (last 30 days)
If i give the input, it is working
femaleldlchdrisk([struct('age',22,'ldl',148,'hdl',20,'systolic',120,'diastolic',94,'hasdiabetes',false,'issmoker',true)])
if I give input as; this is not working
femaleldlchdrisk([struct('age',22,'ldl',148,'hdl',20,'systolic',120,'diastolic',94,'hasdiabetes',false,'issmoker',true) struct('age',42,'ldl',178,'hdl',50,'systolic',140','diastolic',104','hasdiabetes',false,'issmoker',true)])

Your code doesn't support array inputs.
The easy way to deal with this is what I outline below. Note that this is not the optimal method.
function total = femaleldlchdrisk(P)
if numel(P)>1
for n=1:numel(P)
%this assumes a scalar output
total(n)=femaleldlchdrisk(P(n));
end
return
end
%rest of your function goes here
end
