calculatePartialDeterminantKernel

DESCRIPTION

 Compute the Determinant kernel between dynamical systems

 INPUTS
 Takes variable inputs of the type:
   option 1 -  (system1, system2) - two system parameters
   option 2 -  (system1, system2, metricParams) - two system parameters
                and custom values for metric properties
   option 3 -  (M,sigma,system,metricParams) - all-pair solution matrix for
               corresponding sylvester equations, inital state covariance
               estimates, all system parmaeters and metric parameters
               metricParams  -   parameters for computing the Binet-Cauchy kernels
                   .Lambda - Dampening factor for the Binet-Cauchy kernels [Default: 0.9]
                   .Cov_U  - Weight factor for noise covariance [Default: 1]
                   .Alpha  - Weighting Heuristic between two parts of the Binet-Cauchy
                             kernels [Default: 0.5 for no heuristic weighting] 

 OUTPUTS
   kernel  -    kernel between 2 systems or all-pair Partial determinant kernel matrix [N x N]

 EXAMPLE

  kernel = calculatePartialDeterminantKernel(sysParamsCellArray);
