This method is called for expressions of the form
a(b) = c, a{b} = c, a.b = c
and overloading the subsasgn method can allow you to define the meaning of these expressions for objects of class a. These expressions are mapped to a call of the form
a = subsasgn(a,s,b)
where s is a structure array with two fields. The first field is
type is a string containing either '()' or '{}' or '.' depending on the form of the call. subs is a cell array or string containing the the subscript information. When multiple indexing experssions are combined together such as a(5).foo{:} = b, the s array contains the following entries
s(1).type = '()' s(1).subs = {5}
s(2).type = '.' s(2).subs = 'foo'
s(3).type = '{}' s(3).subs = ':'
