substruct
Builds the index structure expected by subsref and subsasgn.
Category: Programming > Classes
Syntax
S = substruct(type1, subs1, ..., typeN, subsN)Returns an N-element struct array, one element per indexing level.
Description
substruct only packages the arguments: the result is a struct array whose type and subs fields are the ones subsref and subsasgn read. The call substruct('.', 'a', '()', {2}) describes the chain .a(2).
A colon is written as the text ':' inside the cell, so substruct('()', {':', 1}) stands for (:, 1).
Input arguments
type- One of
'()','{}'or'.'. subs- For
'()'and'{}', a cell array with one entry per dimension (':'for all). For'.', a field name as text.
Output arguments
S- Struct array with fields
typeandsubs.
Example
A two-level chain
S = substruct('.', 'a', '()', {2})
S(1)
S(2)Output
S = 1×2 struct array with fields:
type
subs
ans = struct with fields:
type: '.'
subs: 'a'
ans = struct with fields:
type: '()'
subs: {[2]}
