COM - Feval() passing a table as a Double[,] is as expected, nonetheless c# Dictionary.ToArray() returns a Double[][] (what is called a jagged array)

What would a best practice be in passing a Dictionary like structure into a matlab function such as "cov" using COM's Feval() ... take the below example:

SortedDictionary<DateTime, Double[]> tableTT;
...
matlab.Feval("cov", 1, out result, tableTT.Values.ToArray());

will fail, as ToArray() returns a jagged array.

Is there a way to avoid using a "conversion" function, such as:

static double[,] ImperativeConvert(double[][] source)
{
    double[,] result = new double[source.Length, source[0].Length];
    for (int i = 0; i < source.Length; i++)
    {
        for (int k = 0; k < source[0].Length; k++)
        {
            result[i, k] = source[i][k];
        }
    }
    return result;
}
