Detailed Description

Quadratic Forward Model.

Test class for the ForwardModel class as defined in oem.h. Implements a quadratic length-m vector valued function in n variables. The function is represented by a set of m-hessians and a Jacobian. On construction those are set to random matrices to test the non-linear OEM methods.

QuadraticModel::QuadraticModel ( Index  m_, Index  n_  )

Constructor.

Construct a random quadratic model. Allocates the necessary space and fille the Jacobian with values in the range [-10,10] and the Hessians in the range [0,0.1]. Also writes all matrices to text files for the communication with the Matlab process.

Parameters

[in]	m_	The dimension of the measurement space.
[in]	n_	The dimension of the state space.
