Matlab的源码是function final_perf = netcalculator(perf, lev, m_fee, p_fee, rf)
% perf 是一个double数组
% lev是一个double
% m_fee是一个double
% p_fee是一个double
% rf是一个double

using netperfcal;   //


private void button3_Click(object sender, EventArgs e)
        {
            // declare vectors
               MWNumericArray Leverage = double.Parse(textBox2.Text);;
               MWNumericArray RiskFreeRate = double.Parse(textBox5.Text);
               MWNumericArray ManagementFee = double.Parse(textBox3.Text);
               MWNumericArray PerformanceFee = double.Parse(textBox4.Text);
               MWArray[] vector = null;
               MWArray[] argOut = null;

            if (dataGridView1.DataSource != null)
            {

                for (int i = 0; i < dataGridView1.RowCount - 1; i++)
                {
                    vector = double.Parse(dataGridView1.Rows.Cells[1].Value.ToString()); // 出错!vector的数据来自dataGridView1  
                }
            }

            netperfcalclass calculation = new netperfcalclass();
            argOut = ("vector", "db_Leverage", "db_ManagementFee", "db_PerformanceFee", "db_RiskFreeRate");    //出错!

            for (int j = 0; j < dataGridView1.RowCount - 1; j++)
            {
            // int row = dataGridView2.Rows.Add();
                dataGridView2.Rows[j].Cells[1].Value = argOut[j];
            }

请麻烦大家帮我看看吧!

vector = double.Parse(dataGridView1.Rows.Cells[1].Value.ToString()); // 出错!vector的数据来自dataGridView1
vector作为一个数组是不是能这样引用的，须用数组名[下标]的方式，另外，数组未初化，使用前必须初始化数组的大小。

argOut = ("vector", "db_Leverage", "db_ManagementFee", "db_PerformanceFee", "db_RiskFreeRate");    //出错!
参数全是字符串，看来和开始说的函数原型的参数类型不一致。另外看下()函数是不是返回一个数组？

1。 可以给个例子吗？Vector应该怎么定义

2。 ()函数返回的是一个数组。


argOut = ("vector", "db_Leverage", "db_ManagementFee", "db_PerformanceFee", "db_RiskFreeRate");
改为
argOut = ((MWArray)vector, (MWNumericarray)Leverage, (MWNumericarray)ManagementFee, (MWNumericarray)PerformanceFee, (MWNumericarray)RiskFreeRate);

请在帮忙一下

MWArray[] vector = new  MWArray[dataGridView1.Rows.Count];
argOut = (vector, Leverage, ManagementFee,PerformanceFee,RiskFreeRate);
