Create a structure array.

S = struct("a",[1;2;3],"b",ones(3),"c",magic(3))

S = struct with fields: a: [3×1 double] b: [3×3 double] c: [3×3 double]

Determine if S is a structure array.

Convert the structure array to a table.

T=3×3 table a b c
_ ___________ ___________

1    1    1    1    8    1    6
2    1    1    1    3    5    7
3    1    1    1    4    9    2

Verify that T is not a structure array.
