string - Scilab 将单元格从矩阵转换为字符串

Question

你好，我是 Scilab 的初学者，我有家庭作业处理测量值，这些值保存在 csv 文件中。这是该文件中的值的示例：

&quot;Project Name:,&lt;Empty&gt;&quot;<br />
&quot;Company Name:,&lt;Empty&gt;&quot;<br />
&quot;User Name:,&lt;Empty&gt;&quot;<br />
&quot;Job Title:,&lt;Empty&gt;&quot;<br />
&quot;Location:,&lt;Empty&gt;&quot;<br />
&quot;Remarks:,&lt;Empty&gt;&quot;<br />
&quot;Date_Time,Test ID,Value_A,Unit_A,Function_A,MeterID_A,BluetoothID_A,Remarks_A&quot;<br />
&quot;2021-03-11 16:59:54,TP0,1968.2,Ω,Res,U1252B-MY52430232,U1177A-238EBF,&quot;<br />
&quot;2021-03-11 16:59:55,TP1,1967.6,Ω,Res,U1252B-MY52430232,U1177A-238EBF,&quot;<br />

我正在尝试使用这些命令仅获取电阻值：

 dates = mgetl('NTC2k2.csv') 
[start, final, match] = regexp(dates(1:$,1)),'/[1-9.]*,Ω/')

但是我的大问题是，当我尝试使用此代码时，它会抛出函数 regexp 无法与矩阵日期（1：$，1）一起使用的异常，请我不知道下一步如何进行。请帮助我，非常感谢！
