Section: Array Generation and Manipulations
This function can be used to index into basic array types (or structures). It provides a functional interface to execute complex indexing expressions such as a.b(3){5}
at run time (i.e. while executing a script or a function) without resorting to using eval
. Note that this function should be overloaded for use with user defined classes, and that it cannot be overloaeded for base types. The basic syntax of the function is:
b = subsref(a,s)
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 b = a(5).foo{:}
, the s
array should contain the following entries
s(1).type = '()' s(1).subs = {5} s(2).type = '.' s(2).subs = 'foo' s(3).type = '{}' s(3).subs = ':'
