type

Arguments

x

a Scilab object.

i

an integer.

Description

type(x) returns an integer which is the type of x as following:

1

a real or complex matrix of double.

2

a polynomial matrix.

4

a boolean matrix.

5

a sparse matrix.

6

a sparse boolean matrix.

7

Matlab sparse matrix

8

a matrix of integers stored on 1 (int8), 2 (int16) or 4 (int32) bytes.

9

a matrix of graphic handles.

10

a matrix of character strings.

11

an un-compiled function (Scilab code). A function created with deff with argument 'n'.

13

a compiled function (Scilab code).

14

a function library.

15

a list.

16

a typed list (tlist).

17

a matrix oriented typed list (mlist).

128

a pointer (Use case: lufact).

129

a size implicit polynomial used for indexing.

130

a built-in Scilab function, called also gateway (C, C++ or Fortran code).

0

a null variable. It is mainly used internally by Scilab. If a function has no declared returned argument like disp when it is called it returns a null variable. If a function is called with an omitted argument in the argument list like foo(a,,b) the missing argument is assigned to a null variable.

Note that if a null variable is assigned to a name, it is removed. x=disp(1) deletes x.

Please note that, for some variables, type will return tlist or mlist due to the internal data structure. This is the case of rational and state-space matrices, hypermat and struct. Please considering the use of typeof instead.
