typeof
explicit type or overloading code of an object
Syntax
t = typeof(object) oc = typeof(object, "overload")
Arguments
 object
a Scilab object
 t
a string (may have spaces): the name of the type of
object
 oc
a string (without spaces): the name of the overloading code for the
object
.
Description
t = typeof(object)
returns one of the following strings:
string  object is a matrix or hypermatrix made of
characters and texts.  
boolean  object is a
boolean matrix or hypermatrix.  
int8 or int16 or int32 or int64 or uint8 or uint16 or uint32 or uint64  
object is a matrix or hypermatrix of [unsigned]
integers stored
on 8, 16, 32 or 64 bits. (see inttype)  
constant  object is matrix or hypermatrix of
decimal or complex numbers.  
polynomial  object is a matrix or hypermatrix of
with decimal or complex coefficients.  
rational  object is a matrix or hypermatrix of
rational
fractions (e.g. transfer matrix), with decimal or complex coefficients.  
handle  object is a graphics
handle.
The subtype of graphics handles (Figure, Axes, Polyline,
Compound, etc) is available in their .type
property. See examples below.  
list  object is a list.  
st  object is a
structure
or a nDarray of structures.  
ce  object is a
cell or a nDarray of cells.  
boolean sparse  object is a
.
 
sparse  object is a
of decimal or complex numbers.
 
fptr  object is a builtin Scilab function,
called also gateway
(C, C++ or Fortran code), a.k.a. a primitive.  
function  object is a function
(Scilab code). See also deff.  
library  object is a
library
of functions in Scilab language.  
pointer  object is a pointer. See a use case:
.  
implicitlist  object is an implicit list using a
polynomial as formal index, for indexing.
See n:$
: (colon)  
listdelete  is returned by
typeof(
.
See null().  
void  is the typeof undefined elements in lists.  
Typed TLists or MLists:  
Note that if the object is a
tlist
or a mlist, typeof
will return the corresponding customized type stored in as a
string in the first list entry.  
Reserved TList or MList types predefined in Scilab:  
dir  object is the result of a
dir()
instruction, with fields name , date ,
bytes , and isdir .  
statespace  object is a statespace model
(see ).  
program  object is a list describing the internal code of a function
(see macr2tree).  
cblock  object is a block of columns of same
heights but of different data types, as returned by
mfscanf.  
XMLDoc  object is an XML Document created with
,
,
, or
.
Additional XML typeof are defined.  
H5Object  object is the id of an HDF5 file opened
with h5open.
Additional HDF5 typeof are defined:
See HDF5 Objects.  
uitree  object is a tree, a branch or a leaf as created with a
uitree feature. See for instance uiCreateNode.  
Reserved Tlist types used in Xcos :  
object is a Xcos block.  
object is a tlist containing the compilation results of a Xcos diagram.  
object is a tlist defining a Xcos diagram: initial parameters,
set of blocks, of links between blocks, and of Text labels belonging to the diagram.  
object is a tlist assigned to the .graphics
field of a block.  
object is a tlist defining and configuring a link between 2 blocks.  
object is a tlist assigned to the .model field
of a block.  
object is a tlist containing some configuration parameters of a
Xcos diagram.  
scsopt  object is a tlist containing the graphical options of the Xcos
diagram editor.  
object is a tlist containing static results of the compilation of
a Xcos diagram.  
object is a tlist containing dynamical results during a Xcos
simulation.  
Text  object is a tlist defining a text label in a Xcos diagram.
