Explanation of L2 norm of an error

When solving for the sparsest possible set of DEs, it is likely our found model will not describe the data exactly - there will be an error

Therefore we can measure the error and give the user it's $l^2$-norm

  • The error is a vector of errors at each time-step
  • More information regarding the $l^2$-norm is here

When working with 2 or more dimensional data, the $l^2$-norm returned will be vector of $l^2$ norms in each coordinate
