Determine if input is table
tf = istable(A)
tf = istable(A) returns logical 1 (true) if A is a table, and logical 0 (false) otherwise.

Create a table, T.
T
T = table(categorical(["M";"F";"M"]),[45 45;41 32;40 34],... ["NY";"CA";"MA"],[true;false;false])
T=3×4 table Var1 Var2 Var3 Var4 ____ ________ ____ _____ M 45 45 "NY" true F 41 32 "CA" false M 40 34 "MA" false
Verify that T is a table.
tf = istable(T)
tf = logical 1
Extract the second and fourth variables from T. When you index into a table using smooth parentheses, the result is a table.
T2 = T(:,[2 4])
T2=3×2 table Var2 Var4 ________ _____ 45 45 true 41 32 false 40 34 false
tf = istable(T2)
Extract data from the second and fourth variables. When you index into a table using curly braces, the result is a matrix, not a table.
A = T{:,[2 4]}
A = 3×3 45 45 1 41 32 0 40 34 0
tf = logical 0
