Math.NET 3.9.0 更新，C# 數學計算包

Math.NET的目標是為提供一款自身包含清晰框架的符號運算和數學運算/科學運算，它是C#開發的開源類庫。Math.NET含了一個支持線性代數的解析器，分析復雜微分，解方程等等功能。

Math.NET Numerics v3.9.0 更新：

3.9.0 - 2015-11-25

• Distributions: Normal.CDF avoids problematic subtraction by using Erfc instead of Erf.
  
• Statistics: geometric and harmonic mean.
  
• Statistics: DataContracts for ephemeral serialization on RunningStatistics, DescriptiveStatistics and Histogram.
  
• BUG: Statistics: Histogram did not adjust lower bound correctly when value was equal to the bound ~Volker Breuer
  
• Linear Algebra: minor optimization on how we call Array.Copy.
  
• BUG: Linear Algebra: fix bug in Complex and Complex32 SparseMatrix.ToTypeString. </p>
