求助，如何读取文本数据

xiaoerh

文本文档内容如下，求教如何在matlab中读取‘Real mass =’，‘Real max_bar_stress = ’，‘Real max_vonmises =’，‘Real frequency = ’后的数值
!
! VARIABLES
!
String section_number[3] = "  6" !
Integer thickness = 9 !
!
! OUTPUTS
!
Real mass = 4995588.0 ---> Mass !
Real max_bar_stress = 1.189315E+2 ---> At Element 737 !
Real max_vonmises = 3.993584E+1 ---> At Element 321 !
Real frequency = 0.02003384 ---> Frequency !

1. textscan
2. regexp
3. 低级格式去读
帮助文件里面都有介绍

blackbutter

fid=fopen('----------.txt');
data=fscanf(fid,'%s');
index1 = findstr(data_iq,'Real mass =');
index2 = findstr(data_iq,'Real max_bar_stress =');
index3 = findstr(data_iq,'Real max_vonmises =');
index4 = findstr(data_iq,'Real frequency =');
%%%%%%%%%%%%%找到数据位置后就可以读取了%%

data1=data(index1+1);
......

regexp是否是正则表达式
而textscan是一部字符串处理呢？

干嘛那么麻烦啊
直接用load
A=load（ filename）;
X=A(2:,1);
y=A(2:,2);
