Create a table, 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.

Create a table, 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

Extract the second and fourth variables from T. When you index into a table using smooth parentheses, the result is a table.

T2=3×2 table Var2 Var4 ________ _____

45    45    true 
41    32    false
40    34    false

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 = 3×3

45    45     1
41    32     0
40    34     0
