Sorry if this is a dumb question...
I would like to upgrade from an older version to current Numerics library.
I have lots of code of the form:
double[][] ActualGaps = new double[10][];
// ... fill in ActualGaps
Matrix mB = new Matrix(ActualGaps); //create B from 10 row, 1 column array
New version of Numerics requires something like
Matrix<double> mB = new Matrix(ActualGaps); //create B from 10 row, 1 column array
But that's still not correct; right side generates error:
Error 1 Using the generic type 'MathNet.Numerics.LinearAlgebra.Matrix<T>' requires 1 type arguments
What's the correct syntax?
Thanks!

You'll find some examples how matrices can be created in the docs:
Creating Matrices and Vectors. Assuming your jagged array is organized by rows (i.e. the outer index is the row index):
Matrix<double> mB = Matrix<double>.Build.DenseOfRowArrays(ActualGaps);
// or
Matrix<double> mB = DenseMatrix.OfRowArrays(ActualGaps)
Thanks,
Christoph



Thanks Christoph, I eventually figured this out...
Got tripped up by a number of very incompatible changes for which I found no documentation,
but all working OK now.
Thanks again,
Best Regards, Dave
