通过Matlab读取/加载不规则文件的一部分 [英] read/load parts of the irregular file by Matlab

问题描述

我想通过matlab部分加载PTX文件(请参见以下示例)

I would like to partly load a PTX file by matlab (please see the following example)

我需要将前两行(2个数字)读写到2个变量中，例如a和b.并将第5行到末尾的数据读写到一个矩阵中

I need to read and write the first two row (2 numbers) into 2 variables say a and b. And read and write the data from 5th row to the end into a matrix

感谢您的帮助

推荐答案

查看 tdfread 函数，以便将数据导入Matlab.它应该类似于datafile = tdfread(filename, '\t').一旦有了，就索引到该函数返回的变量，如

Look at the tdfread function in order to get the data into Matlab. It should be something like datafile = tdfread(filename, '\t'). Once you have that, index into the variable returned from that function like

a = datafile(1, 1);
b = datafile(2, 1);
data = datafile(5:end, :);
