soerenwolfers commented 4 weeks ago

Description

TryFlattenTo and TryBroadcastTo throw when destination is too short, TryCopyTo returns false.

Reproduction Steps

using System.Diagnostics.CodeAnalysis;
using System.Numerics.Tensors;

namespace ConsoleApp1;

public abstract class Program
{
    [Experimental("SYSLIB5001")]
    public static void Main()
    {

        new TensorSpan<double>(new double[1]).TryCopyTo(Array.Empty<double>());
        new TensorSpan<double>(new double[1]).TryFlattenTo(Array.Empty<double>());
    }
}

Expected behavior

Return false; never throw.
