当我实现接受此按摩的代码时，我尝试使用dlmread，txtscan或textread读取这些数据：

使用dlmread时出错（第139行）文件和格式字符串不匹配。无法从文件中读取数字（第1u行，第1u行）==＆gt; #nMT = 1000000 tmax = 4000 trelax = 1000 k + = 1 k-T = 0.01 k-D = 0.1 kh = 1 \ n

我希望命令读取txt文件并忽略前两行。非常感谢任何帮助。我将感激你。

Answer 1

使用importdata：

x = importdata('file.txt',' ',2); %// ' ': col separator; 2: number of header lines
data = x.data; %// x.data is what you want

第一行为结构x提供data，textdata和colheaders字段。数字数据位于字段data中，因此您需要x.data。

在Matlab中读取txt文件包含两个第一行中的符号
