Yet Another Math Parser (YAMP)

, 30 Sep 2012
Constructing a fast math parser using Reflection to do numerics like Matlab.
 ```﻿using System; using System.Collections.Generic; namespace YAMP { class MaxFunction : StandardFunction { public override Value Perform(Value argument) { if (argument is ScalarValue) return argument; else if (argument is MatrixValue) { var m = argument as MatrixValue; if(m.DimensionX == 1) return GetVectorMax(m.GetColumnVector(1)); else if(m.DimensionY == 1) return GetVectorMax(m.GetRowVector(1)); else { var M = new MatrixValue(1, m.DimensionX); for(var i = 1; i <= m.DimensionX; i++) M[1, i] = GetVectorMax(m.GetColumnVector(i)); return M; } } throw new OperationNotSupportedException("max", argument); } ScalarValue GetVectorMax(MatrixValue vec) { var buf = new ScalarValue(); var max = double.NegativeInfinity; var temp = 0.0; for(var i = 1; i <= vec.Length; i++) { temp = vec[i].Abs().Value; if (temp > max) { buf = vec[i]; max = temp; } } return buf; } } } ```

If a file you wish to view isn't highlighted, and is a text file (not binary), please let us know and we'll add colourisation support for it.
