AccessViolationException: ShoNS.Array.DoubleArray.From( new double[x.Length] )

Question

It looks like calling 'From' to convert an array into a DoubleArray will cause an error to be thrown when MultiplyTo is called.

Test code:

ShoNS.Array.SparseDoubleArray shoSparse = ShoNS.MathFunc.ArrayRandom.RandomSparseDoubleArray(1000,80);

ShoNS.Array.DoubleArray tvSho = ShoNS.Array.DoubleArray.Zeros(80, 1);

ShoNS.Array.DoubleArray xSho = ShoNS.Array.DoubleArray.From( new double[80] ).T;
tvSho.MultiplyInto( shoSparse, xSho );

System.AccessViolationException was unhandled

Answer 1

Also looks like there's a bug in the long signature

a.MultiplyInto(1.0,b, true, c, true, 1.0);

If transpose is true, we get an access memory violation. If false, no violation occurs.

Answer 2

DoubleArray.From(matrix([[1;2;3];[4;5;6;]])) write in this, no error
