typeof

object type

Calling Sequence

[t]=typeof(object)

Arguments

object

a Scilab object

t

a string

Description

t=typeof(object) returns one of the following strings:

"constant"

if object is a real or complex matrix of double.

"polynomial"

if object is a polynomial matrix.

"function"

if object is a function (Scilab code). See also deff.

"handle"

if object is an handle.

"string"

if object is a matrix made of character strings.

"boolean"

if object is a boolean matrix.

"list"

if object is a list.

"rational"

if object is a rational matrix (transfer matrix).

"state-space"

if object is a state-space model (see syslin).

"sparse"

if object is a (real) sparse matrix.

"boolean sparse"

if object is a boolean sparse matrix.

"hypermat"

if object is a hypermatrix (N-dimension array with N<=3.

"st"

if object is a structure.

"ce"

if object is a cell array.

"fptr"

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

"pointer"

if object is a pointer (See an use case: lufact).

"size implicit"

if object is a size implicit polynomial used for indexing. This a purely internal value.

"library"

if object is a function library.

"int8" or "uint8" or "int16" or "uint16" or "int32" or "uint32"

if object is a matrix of [unsigned] integers stored on 8, 16 or 32 bits. (See int)

Note that if the object is a tlist or mlist, typeof will return the first string in the first list entry.

Examples

typeof(1)
typeof(poly(0,'x'))
 
typeof(1/poly(0,'x'))
typeof(%t)
 
w=sprand(100,100,0.001);
typeof(w)
typeof(w==w)
 
deff('y=f(x)','y=2*x');
typeof(f)
 
L=tlist(['V','a','b'],18,'Scilab');
typeof(L)
 
typeof(corelib)
