这是我要隐含的代码，
实际上我正在尝试从文件中读取值并将其传输到k均值算法，但是它通常使用double值，如何将文件中的字符串值转换为k均值所需的double值
我得到的错误是double [] []有一些无效的参数
请帮我解决这个问题

This is the code I am trying to impliment,
Actually I am trying to read values from file and transfer it to k means algorithm, but it oly takes double value,how should I convert string value taken from file to double value required by k means
error i am getting is double[][] had some invalid arguments
please help me out this prob
