Handling Subscripted Assignment
The use of a subscript or field designator with an object on the left-hand side
of an assignment statement is known as a subscripted assignment. MATLAB
calls a method named subsasgn in these situations. Object subscripted
assignment can be of three forms - an array index, a cell array index, and a
structure field name.
A(I) = B
A{I} = B
A.field = B
Each of these results in a call to subsasgn of the form
A = subsasgn(A,S,B)
The first argument, A, is the object being referenced. The second argument,
S, has the same fields as those used with subsref. The third argument, B,
is the new value.
