# Iridium 2008 March Release (v2008.3.12.405)

Iteration 12 of Math.NET Iridium (Numerics) is now available, as 2008 March Release with Version 2008.3.12.405.

**Team:** Christoph Rüegg, Joannès Vermorel, Matthew Kitchin

**New Contributions:** Mike Shugai

#### Summary

**Bugs:**All known 3 bugs have been fixed.**Linear Algera:**Matrix Kronecker product, new Vector class, performance work (caching).**Core:**New Sinc function, Neper/Decibel ratio routines.**Probability Distributions:**New distributions: Student's T-Distribution, F-Distribution, Skew-Alpha Stable Distribution.- Assemblies no longer signed with a certificate (because verification caused network access).

#### New Features

- IRID-113: Core - Neper and Decibel Helper and Factors
- IRID-116: Core - Sinc Function
- IRID-111: Linear Algebra - Matrix Kronecker Tensor Product
- RID-59: Linear Algebra - New Vector class (related to the Matrix class)
- IRID-99: Probability Distributions - New Distribution: Skew Alpha Stable Distribution
- IRID-108: Probability Distributions - New Distribution: F-Distribution
- IRID-109: Probability Distributions - New Distribution: Student's-T

#### Enhancements

- IRID-106: Linear Algebra - Cache for on-demand computations (like decompositions)

#### Fixed Bug

- IRID-107: Core - Complex: Unexpected power behavior at zero
- IRID-97: Linear Algebra - Matrix.Identity allocation bug in non-square cases
- IRID-98: Probability Distributions - ArbitraryDistribution NextInt32 does not consider offset.

#### Other

- IRID-110: Remove Certificate Signing (cert validation causes network access)

Nice to see that new people are joining Math.NET. If I get the time, I will try to submit some Erlang-related formulas and distribution for the next release :-)

Thanks, I'm looking forward to it! :)
