保存/检索DenseMatrix

Question

购买后使用极限优化库 每次我保存以下3x3 DenseMatrix然后检索它，它就变成了0x0矩阵。

我尝试以下方法;谁能解释我做错了什么？

  let matrix_file_debug_print(filepath : String, a : DenseMatrix) = 
    for i = 0 to a.RowCount-1 do
        for j = 0 to a.ColumnCount-1 do
            System.IO.File.AppendAllText(filepath,a.[i,j].ToString()+",")
        System.IO.File.AppendAllText(filepath,"\r\n")
    System.IO.File.AppendAllText(filepath,"********************************\r\n")

let readclient = redisClient.As<DenseMatrix>()
    readclient.Lists.["ConjCommutative33a"].Add(DenseMatrix.Create(3,3))
    readclient.Lists.["ConjCommutative33b"].Add(DenseMatrix.Create(3,3))

    let redisgroupa = readclient.Lists.["ConjCommutative33a"]
    let redisgroupb = readclient.Lists.["ConjCommutative33b"]
    //let redisgroupa = readclient.GetValue("OnlyCommutative33a")
    //let redisgroupb = readclient.GetValue("OnlyCommutative33b")
 for pgi in 0..groupresult1acc3a.Count-1 do
        System.IO.File.AppendAllText(filepath,"$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$New Pair$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$\r\n")
        matrix_file_debug_print(filepath, groupresult1acc3a.[pgi])
        matrix_file_debug_print(filepath, groupresult2acc3b.[pgi])

代码完成，在visual studio中我调试它，计数＆gt; 0并单击要查看的元素 它是0 * 0矩阵
