definedfields

returns an index of list's defined fields

Syntax

k = definedfields(lst)

Arguments

lst

a list, tlist or mlist variable.

k

a vector of index.

Description

If lst is a list, a tlist, a mlist k = definedfields(lst) returns in k the indices of the defined list fields. This function is useful because indexing undefined fields produces an error.

Examples

lst=list(1);lst(3)=5
k=definedfields(lst)

t=tlist('x');t(5)=4
definedfields(t)

m=mlist(['m','a','b']);m.b='sdfgfgd'
definedfields(m)
