MATLAB: Creating new variable using for loop and if-else condition

for loophomework

Hi,
I wish to divide my age data in column vector into age-groups 10-29, 20-29, 30-39, 40-49, 50-59, etc. using for loop and the if-else statements. here what I have started. but i wonder how to create that new variable age group. 
for n=1:length(age)
    if age(n)==10 & age(n)<=29
        new_age_group1 = age() <what to place here>
    elseif age(n)==30 & age(n)<=39
        new_age_group2 = age() <what to place here>
    end       
end

Best Answer

age = 1 : 40; % you were almost close, note: it could be done without loops
[new_age_group1, new_age_group2] = deal(cell(40, 1));
for n = 1 : numel(age) 
    if age(n) >= 10 && age(n) <= 29;
        new_age_group1{n} = age(n); 
    elseif age(n) >= 30 && age(n) <= 39
        new_age_group2{n} = age(n);
    end       
end
new_age_group1 = cat(1, new_age_group1{:})
new_age_group1 = 20×1
    10
    11
    12
    13
    14
    15
    16
    17
    18
    19

new_age_group2 = cat(1, new_age_group2{:})
new_age_group2 = 10×1
    30
    31
    32
    33
    34
    35
    36
    37
    38
    39
