Test Status Code Input and Output
1   Pass
%% trivial case [b2, ix2] = sortg([], @lt); assert(isempty(b2) && isempty(ix2));
2   Pass
%% usual less than a = rand(1, 100); [b1, ix1] = sort(a); [b2, ix2] = sortg(a, @lt); assert(isequal(b1, b2) && isequal(ix1, ix2));
3   Pass
%% descending order a = rand(1, 100); [b1, ix1] = sort(a, 'descend'); [b2, ix2] = sortg(a, @gt); assert(isequal(b1, b2) && isequal(ix1, ix2));
4   Pass
%% small absolute value first a = randn(1, 100) + randn(1, 100)*1i; [~, ix1] = sort(abs(a)); b1 = a(ix1); [b2, ix2] = sortg(a, @(a, b) abs(a) < abs(b)); assert(isequal(b1, b2) && isequal(ix1, ix2));
5   Pass
%% stable sort a = randi(10, 1, 100); [b1, ix1] = sort(a); % MATLAB's sort() is stable [b2, ix2] = sortg(a, @lt); assert(isequal(b1, b2) && isequal(ix1, ix2));
