如何将检测响应读取到CSV文件中

Question

我正在处理MATLAB中的跟踪以及使用在文本文件中提供检测响应的数据集。

我想读取此文件并将其保存在CSV文件中，然后处理CSV文件进行处理。

文本文件信息没有按行排序，数据集中有两个文本文件。其中一个名称为“gt.txt”，另一个名为“det.txt”。

文本文件的示例所示（以逗号分隔）：

1,-1,198,203,62.22,141.19,42.848,-1,-1,-1

Answer 1

所以，问题是你的“CSV文件”是逗号分隔，但新线由空格界定？

fid=fopen('det.txt','rt'); 
str=fread(fid,inf,'uint8=>char') 
result = cell2mat(textscan(str,'%f,%f,%f,%f,%f,%f,%f,%f,%f,%f ')) 
csvwrite('result.txt',result);
