calculateGapDistance

PURPOSE

Compute the Gap distance between dynamical systems

SYNOPSIS

function dist = calculateGapDistance(varargin)

DESCRIPTION

 Compute the Gap distance between dynamical systems

 INPUTS
 Takes variable inputs of the type:
   option 1 -  (angles) - all-pair subspace angles [numAngles x N xN] between
                systems
   option 2 -  (system1, system2) - two system parameters
   option 3 -  (system1, system2, metricParams) - two system parameters
                and custom values for metric properties

 OUTPUTS
   dist     -  distance between two systems or all-pair Gap distance
               matrix [N x N]

 EXAMPLE

   sa = subspaceAnglesAR(sysParamsCellArray);
   dist = calculateGapDistance(sa);
