Zend Framework: Zend_Math Component Proposal

Table of Contents

1. Overview

Zend_Math is a component which contains math related functions and classes. The purpose of this component is to make life easier for people who are doing vector and matrix math for example.

3. Component Requirements, Constraints, and Acceptance Criteria

• This component will support helper methods such as "clamp" and "lerp".
• This component will support vector classes to do vector math.
• This component will support matrix classes to do matrix math.
• This component will support functionality to detect intersections.

4. Dependencies on Other Framework Components

• Zend_Exception
• SPL Iterator
• SPL Exceptions

5. Theory of Operation

This component can be used as is. It can be used to do calculations.
