map seems to work differently on lists and Matricies.  How do I get map to work on the Matrix?

a := [[1.2, 4.3], [3.2, 5.3]]

[[1.2, 4.3], [3.2, 5.3]]

 (1)

whattype(a)

list

 (2)

a[1]

[1.2, 4.3]

 (3)

b := map(proc (x) options operator, arrow; [floor(x[1]), x[2]] end proc, a)

[[1, 4.3], [3, 5.3]]

 (4)

c := convert(a, Matrix)

Matrix(%id = 36893488148073393796)

 (5)

whattype(c)

Matrix

 (6)

c[1]

Vector[row](%id = 36893488148073381388)

 (7)

d := map(proc (x) options operator, arrow; [floor(x[1]), x[2]] end proc, c)

Matrix(%id = 36893488148073382844)
