在MATLAB中解析文本文件 [英] parse text file in MATLAB

问题描述

如何在MATLAB中解析文件?文本中的数据具有以下格式:

How can I parse file in MATLAB? The data in the text has this format:

p
15.01245  20.478
12.589  58.256
n
16.589  87.268
52.367  46.256
2.589  58.02

我想将每个数据存储在 单独的数组 ( ie 中；将数据存储在字母p下的数组1中，并将数据存储在字母n下在数组2中).

I want to store each data in separate array (i.e; store data under letter p in array 1, and data under letter n in array 2).

有什么帮助吗?

推荐答案

这是另一种解决方案:

fstring = fileread('test.txt'); % read the file as one string
fblocks = regexp(fstring,'[A-Za-z]','split'); % uses any single character as a separator
fblocks(1) = []; % removes anything before the first character
out = cell(size(fblocks));
for k = 1:numel(fblocks)
    out{k} = textscan(fblocks{k},'%f %f','delimiter',' ','MultipleDelimsAsOne', 1);
    out{k} = horzcat(out{k}{:});
end
