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

A = subsasgn(A,S,B)

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:

type: A string containing '()', '{}', or '.', where '()' specifies integer subscripts; '{}' specifies cell array subscripts, and '.' specifies subscripted structure fields.
subs: A cell array or string containing the actual subscripts.

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}`
