Detailed Description

template<typename Value>
class OpenMS::Matrix< Value >

A two-dimensional matrix. Similar to std::vector, but uses a binary operator(,) for element access.

Think of it as a random access container. You can also generate gray scale images. This data structure is not designed to be used for linear algebra, but rather a simple two-dimensional array.

The following member functions of the base class std::vector<ValueType> can also be used:

• begin
• end
• rbegin
• rend
• front
• back
• assign
• empty
• size
• capacity
• max_size
