如何从 MATLAB 中的文本文件创建矩阵? [英] How do you create a matrix from a text file in MATLAB?

问题描述

我有一个有 4 列的文本文件，每列有 65536 个数据点.行中的每个元素都用逗号分隔.例如:

I have a text file which has 4 columns, each column having 65536 data points. Every element in the row is separated by a comma. For example:

X,Y,Z,AU
4010.0,3210.0,-440.0,0.0
4010.0,3210.0,-420.0,0.0
etc.

所以，我有 65536 行，每行有 4 个数据值，如上所示.我想将其转换为矩阵.我尝试将数据从文本文件导入到 Excel 文件中，因为这样很容易创建矩阵，但我丢失了一半以上的数据.

So, I have 65536 rows, each row having 4 data values as shown above. I want to convert it into a matrix. I tried importing data from the text file to an excel file, because that way its easy to create a matrix, but I lost more than half the data.

推荐答案

如果文件中的所有条目都是数字，则可以简单地使用 a = load('file.txt').它应该创建一个 65536x4 的矩阵 a.它甚至比 csvread

If all the entries in your file are numeric, you can simply use a = load('file.txt'). It should create a 65536x4 matrix a. It is even easier than csvread
