使用MATLAB从csv文件读取字符串列

Question

I have the following data in a csv file:

00:1A:1E:35:81:01,  -36,    -37,    -36
00:1A:1E:35:9D:61,  -69,    -69,    -69
00:1A:1E:35:7E:C1,  -95,    -95,    -71
00:1A:1E:35:9D:65,  -66,    -67,    -67
00:1A:1E:35:9D:60,  -67,    -68,    -68
00:1A:1E:35:9D:63,  -66,    -68,    -68

I am unable to read first column with MATLAB, which contain strings.

Answer 1

You can use

xlsread(file.csv); 

instead of csvread. It returns [num, txt, raw], where num contains all cells parsed to double (NaN where it was not possible), txt all cells as text ('' where conversion to num succeeded) and raw with all cells as strings.
