what wrong I am doing in the code?

i have to filter out female above age 30 and less than 40 fron the give data base

'name', {'mary','john','anna','paul','elaina'},

'gender',{'f', 'm', 'f', 'm', 'f'},

'age' ,{25, 35, 30, 22, 38}

Using structure method

function [patient] = filterpatients_struct(data)
t=array2table(data(2:end,:),'gender',data(1,:));
t.name=string(t.name);
t.gender=categorical(t.gender);
t.age=cell2mat(t.age);
t.name(t.gender=="f");
patient = t.name(t.gender=="f");

% Make required structure 
S = struct ; 
S.name =  {'mary','john','anna','paul','elaina'}  ;
S.gender = {'f',   'm',   'f',   'm',   'f'} ; 
S.age  = [25,    35,    30,    22,    38]  ; 

idx = strcmp(S.gender,'f') ;   % Indices of females 
iwant = S.age(S.age(idx) >=30 & S.age(idx) <= 40 )   % age criteria

this will only work if i manually input the values. i want to call a function so that if i ask in cammand window to display.

function [patient] = filterpatients_struct(data)
S.name = strcmp(data(1,:),'name');
S.gender = data(strcmp(data(2,:),'gender'),1);
S.age = data(strcmp(data(3,:),'age'),1);
idx = strcmp(S.gender,'f') ;   % Indices of females 
iwant = S.age(S.age(idx) >=30 & S.age(idx) <= 40 );   % age criteria 

patient = iwant;

You can write a function for that..not a big deal.

this is not working i tried

Why it will not work? What input you want to give to function and what you are expecting output?

[Manav Divekar]

input

disp(filterpatients_struct( struct( ...

'name', {'mary','john','anna','paul','elaina'}, ...

'gender',{'f', 'm', 'f', 'm', 'f'}, ...

'age' ,{25, 35, 30, 22, 38} ) ));

expected value 'anna' 'elaina'

Write the given code into a a function.
