How to successfully deploy Matlab function [B, IX] = sort (A, ...)
IX is a permutation vector of the corresponding column of A
M := Matrix(6, 3, [2, 3, 3, 5, 7, 8, 12, 5, 9, -3, 4.1, 7, 7, 7, -3, 9, 3, 8]):
M;
L := <(seq(op(convert(sort(M[() .. (), j]), list)), j = 1 .. op(M)[2]))>;
L := ArrayTools[Alias](L, [op(M)[1 .. 2]], Fortran_order);
P := Matrix(op(M)[1 .. 2], (i, j)-> ListTools[Search](L[i, j], M[() .. (), j]));
# from Matlab
# [b,n]=sort(A)
# b =
# -3.0000 3.0000 -3.0000
# 2.0000 3.0000 3.0000
# 5.0000 4.1000 7.0000
# 7.0000 5.0000 8.0000
# 9.0000 7.0000 8.0000
# 12.0000 7.0000 9.0000
# n =
# 4 1 5
# 1 6 1
# 2 4 4
# 5 3 2
# 6 2 6
# 3 5 3
#
