get a tlist, mlist or struct fields names


f = fieldnames(lst)



A tlist, mlist or struct variable.


Strings column vector of fields names.


The fieldnames function returns field names of a tlist, mlist or struct. fieldnames does not work on cells.

As said in rational or syslin help pages, internal representation of some Scilab objects is a tlist (or rlist), so using fieldnames with them will return the generic forms of these objects. For example, for rationals, the function will return "num","den" and "dt".


fieldnames(tlist(['listtype', 'f1', 'f2'], [], []))
fieldnames(mlist(['V', 'key', 'value'], ['a' 'b' ; 'c' 'd'], [1 2 ; 3 4]))
fieldnames(struct('f1', 25, 'month', 'DEC', 'year', 2006))
obj.x = 3;
obj.y = 3;
