回答： dpb 2017-6-29

I am using textscan to read a file. The data of file is something like:

ASC2007252381128.0000.T88.ch04.sac E
ASC2007252381128.0000.T90.ch04.sac A

and so on.

I am having problems in defining formatspec to be used in textscan. I tried reading it by using fileread which converts it into a string array of single cell. I wish to obtain just the string before a blank i.e,

ASC2007252381128.0000.T90.ch04.sac,ASC2007252381128.0000.T88.ch04.sac

and so on. Can anybody please help me with the problem? Thanks

在 MATLAB Online 中打开

>> s='ASC2007252381128.0000.T88.ch04.sac E';   % sample input record
>> fmt='%s %*s';                               % read a string, skip a string
>> textscan(s,'%s %*s')                        % read it..
ans = 
  {1x1 cell}
>> ans{:}
ans = 
  'ASC2007252381128.0000.T88.ch04.sac'
