Thread Subject: extracting data from long message

Hello,

I have a long message, I want to extract data groups from
this messsage and save each one separately. Foe example,

MSG= ('12.34 05/06/06 : computer-group: network-groups')

Not the separation beween each group is : . I need to
store each grop separately in other messages or arrays!

submessages = textscan(MSG, '%s', 'Delimeter', ':')

Hi walter,

I get the message "??? Error using ==> textscan
First input must be of type double."

I am using Matlab 7.

Thanks

because, this should have read

     msg='12.34 05/06/06 : cg: ng';
     sm=textscan(msg,'%s','Delimiter',':'); % <- typo
     sm{:}
% ans =
% '12.34 05/06/06 '
% 'cg'
% 'ng'

try

     msg='12.34 05/06/06 : cg: ng';
     sm=strread(msg,'%s','delimiter',':');
     sm
% sm =
% '12.34 05/06/06 '
% 'cg'
% 'ng'
