Christoph Ruegg	43c4608cce	Solution: extract IO into separate IO project Linear Algebra comes with a set of IO classes for reading and writing text files as well as files compatible with Matlab. These classes have now been extracted into a separate MathNet.Numerics.IO project and assembly. The core project no longer has zlib.net as dependency (only Numerics.IO has).	15 years ago

Christoph Ruegg	d15f592f3e	Normal Distribution: fix Variance property setter The variance setter was passing the variance as standard distribution, instead of its square root. Reported by Peter126 at Codeplex.	15 years ago
Alexander Karatarakis	2a8ae87765	Seal ConjugateTranspose() for double/single and remove redundant overrides For non-complex matrices, the ConjugateTranspose is the same as the transpose. Therefore, a sealed override for ConjugateTranspose() that simply forwards the call to Transpose() makes sense for double/single matrices.

cureos	07ddec8a31	Assembly.Load in CompositeSolver classes use the assembly name string to avoid build errors in Silverlight 5. Fixes issue #27 in mathnet fork	15 years ago
seahearman	01a26e9cb2	I want to sample a vector from a multivariate normal distribution. According to the Help file, I should use the method Sample(), but I found out that I can only sample a square matrix from this method, that is when I use the following code: var NRow = 3; var NCol = 3; var m = new DenseMatrix(NRow, NCol); var v = new DenseMatrix(NRow); for (var i = 0; i < NRow; i++) { v[i, i] = 1; } var k = new DenseMatrix(NCol); for (var i = 0; i < NCol; i++) { k[i, i] = 1; } var NewMatrix = new MatrixNormal(m, v, k); var Sampleone = NewMatrix.Sample(); It is fine, but when I change NRow=4, (but keep NCol=3) it does not work. I checked the code, I think the problem is in MatrixNormal.cs Line 286: var vector = SampleVectorNormal(rnd, new DenseVector(n * n, 0.0), vki); but I think it should be: var vector = SampleVectorNormal(rnd, new DenseVector(n * p, 0.0), vki);	15 years ago

Andrew Kazyrevich	622e5277f3	Minor improvement. Exception messages for matrix dimensions now tell you the values (in addition to a mere 'dimensions must match' we had before).	15 years ago

Gustavo Guerra	934df455f3	added unit tests for mapCols, mapRows, sumColsBy and sumRowsBy	15 years ago
Christoph Ruegg	7a34beed26	Sparse Vectors: Equals now supports accidential zeros. Fixes gh-21. Equals previously returned always false in case of (asymmetric) accidential zeros. Instead, Equals now expects accidential zeros and treats them correctly (so we can allow arithmetic algorithms to generate accidential zeros, avoiding a lot of zero checks).	15 years ago
Christoph Ruegg	a8f21270b7	Unit Tests: confirming gh-21 on sparse accidantial zero/Equals inconsistency	15 years ago

Christoph Ruegg	7b47fb50e3	Sparse Linear Algebra: complex vectors now override right Equals. gh-20. Previously sparse vectors for Complex and Complex32 did override Object.Equals instead of the generic IEquatable<Vector<T>>.Equals. Now only overrides the generic version to ensure that the right version is called in all code paths.	15 years ago

Christoph Ruegg	7cced98dd2	Threading: CommonParallel now supports empty loops. Closes gh-19. CommonParallel did break on empty loops with an argument exception instead of just doing nothing. It now exits early if there's nothing to do in For and Invoke, no longer throwing an exception. Also, it now special cases single-element iterations and inlines their execution (trivial loop unrolling), skipping all the threading/task overhead.	15 years ago
