在matlab中读取CSV文件 [英] Reading CSV file in matlab

问题描述

我有一个csv文件，像这样的格式：

I have a csv file like this format:

2.3 , 1.3 , 1.2 , 6.8 , classone
1.2 , 2.6 , 1.8 , 0.7 , classtwo

我想将文件读入seprate矩阵;一个矩阵中的前4个数字值和另一个矩阵中的字符串值

I want to read the file into seprate matrix; the first 4 numeric values in one matrix and the string value in another matrix

我尝试了textscan函数，但它不能很好地工作

I have tried textscan function but it doesnt work well

M= textread('training.dat','%f %f %f %f %s');

Error using dataread
Number of outputs must match the number of unskipped
input fields.

推荐答案

尝试

[num, str, ~] = xlsread('training.dat');

fid = fopen('training.dat');
D = textscan(                                ...
        fid,                   '%f%f%f%f%s', ...
        'Delimiter',           ' , ',        ...
        'MultipleDelimsAsOne', true          ...
);
fclose(fid);

numeric_stuff = horzcat(D{1:4});
string_stuff  = D{5};
