subsasgn

Purpose

Overloaded method for A(i)=B, A{i}=B, and A.field=B

Syntax

Description

A = subsasgn(A,S,B) is called for the syntax A(i)=B, A{i}=B, or A.i=B when A is an object. S is a structure array with the fields:

Examples

The syntax A(1:2,:)=B calls A=subsasgn(A,S,B) where S is a 1-by-1 structure with S.type='()' and S.subs = {1:2,':'}. A colon used as a subscript is passed as the string ':'.

The syntax A{1:2}=B calls A=subsasgn(A,S,B) where S.type='{}' .

The syntax A.field=B calls subsasgn(A,S,B) where S.type='.' and S.subs='field'.

These simple calls are combined in a straightforward way for more complicated subscripting expressions. In such cases length(S) is the number of subscripting levels. For instance, A(1,2).name(3:5)=B calls A=subsasgn(A,S,B) where S is 3-by-1 structure array with the following values:

S(1).type='()'

S(2).type='.'

S(3).type='()'

S(1).subs={1,2}

S(2).subs='name'

S(3).subs={3:5}
