Hi,

I am using Iridium library with F# for some numerical computations. F# is a functional language that uses type inference during compilation. It does not support explicit casting as in C#. So my problem is following. Sometimes I do not explicitly state type for some variables, relying on type inferencing. By inferencing F# will assign Matrix class type to my variable and there is no way to get double[,] type through implicit casting. The only one work around is to state method, that will provide explicit type reference.

Please, include following code into the library for grater compatibility:

public double[,] ToArray()

{

double[,] newData = new double[m.RowCount, m.ColumnCount];

for (int i = 0; i < _data.RowCount; i++)

for (int j = 0; i < _data.ColumnCount; j++)

newData[i, j] = _data[i, j];

return newData;

}

Sincrely,
Art
