FSALoadNumericalResults

FSALoadNumericalResults[files] is a simple function that loads numerical results generated by the FIESTA script created via FSAPrepareSDEvaluate into Mathematica. The argument files is the output of FSAPrepareSDEvaluate that contains the full paths to FIESTAScript.m and the output file.

The optionChop (set to 10^(-10) by default) tells the function to remove numerical artefacts.
