Utility Library Classes
Field name only This format may be used only in the case of a
1-by-1 structure array and returns the named
field’s value. For example:
x("red") = 0.2
x("green") = 0.4
x("blue") = 0.6
In this example, the name of the Item
property was neglected. This is possible since
the
Item property is the default property
of the
MWStruct class. In this case the t wo
statements are equiv a lent:
x.Item("red") = 0.2
x("red") = 0.2
Single index and field name This format accesses array elements
through a single subscripting notation. A
single numeric index
n followed by the
field name returns the named field on
the
nth array element, navigating the
array linearly in column-major order.

statements are equiv a lent:
