You are working at a hospital's IT department. The hospital is recruiting patients for clinical trial of a new drug. In the current phase of the clinical trial, only female patients between the ages of 30 (inclusive) to 40 (inclusive) are being recruited. Your boss wants you to filter out the database of volunteer patients and extract the names of those matching the criteria. Write a function filterpatients that takes as input the list of patients in the database as a struct array and returns the names of eligible patients as a cell array of strings. Assume that the gender is always given in lower case, either as 'f' or 'm'.

>> disp(filterpatients(struct( ... 'name', {'mary','john','anna','paul','elaina'}, ... 'gender',{'f', 'm', 'f', 'm', 'f'}, ... 'age' ,{25, 35, 30, 22, 38} ) )); 'anna' 'elaina' >> disp(filterpatients(struct( ... 'name', {'mary','john'}, ... 'gender',{'f', 'm'}, ... 'age' ,{37, 35} ) )); 'mary'
