Using the C++ Math Library

Overview

You can use any indexing expression - an array together with one or more subscripts - as the target of an assignment statement. An assignment statement consists of a destination to the left of the equals (=) operator and a source to the right. When the destination is an indexing expression, the indexing expression selects the elements that are to be modified; the source specifies the new values for those elements.

You can use five different kinds of indices:

• Scalar
• Vector
• Matrix
• Colon
• Logical

The examples below do not present all the possible combinations of these index types.

Note    The size of the destination array (after the subscript has been applied) and the size of the source array must be the same.
