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. 

tf = isstruct(S)
tf = logical
   1

Convert the structure array to a table.

T = struct2table(S)
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. 

tf = isstruct(T)
tf = logical
   0
