如何从Matlab中的文本文件读取矩阵 [英] how to read a matrix from a text file in matlab

问题描述

我有一个文本文件，该文件具有数字(整数)值的500 columns和500 rows.该行中的每个元素都由一个制表符分隔.我想将此文件读取为matlab中的矩阵.示例(我的文本文件是这样的):

I have a text file which has 500 columns and 500 rows, of numerical(integer) values . Every element in the row is separated by a tab. I want to read this file as a matrix in matlab. Example(my text file is like this):

 1 2 2 1 1 2 
 0 0 0 1 2 0
 1 2 2 1 1 2 
 0 0 0 1 2 0

然后在matlab中读取此文本文件作为矩阵(a[])后，我想做transpose. 救救我.

And after reading this text file as a matrix (a[]) in matlab I want to do transpose. Help me.

推荐答案

您可以使用importdata. 像这样:

You can use importdata. Something like:

filename = 'myfile01.txt';
delimiterIn = '\t';
headerlinesIn = 1;
A = importdata(filename,delimiterIn,headerlinesIn);
A_trans = A';

如果文件没有任何杂音，则可以跳过标题行.(这是实际数据开始之前的行数)

You can skip headerlines if your file does not have any haeder.. (It is the number of lines before the actual data starts)
