Some examples of usage:

% Sort numerical array in descending order

A=rand(1,100000); tic; [As,is]=qsort(A, @(x,y) y-x); toc

% Sort strings

s = string(randi(200,1,20))

ss = qsort(s, @(x,y) double(x)-double(y))

% Sort structures

s = struct('name',{'smith' 'jackson' 'anna'},'yearofbirth', {40 70 60});

ss = qsort(s, @(x,y) x.yearofbirth-y.yearofbirth);

{ss.name} % returns {'smith'} {'anna'} {'jackson'}

[ss.yearofbirth] % returns 40 60 70

% Sort cell array

c = num2cell(struct('name',{'smith' 'jackson' 'anna'},'yearofbirth', {40 70 60}));

cs = qsort(c, @(x,y) x{1}.yearofbirth-y{1}.yearofbirth);
