That was a good attempt, but for this you should use tokens:
buffer = fileread( 'SnSe_100K_17.out' ) ;
pattern = ':\s+(\S+)\s+([^\(]+)\D+(\S+)' ;
tokens = regexp( buffer, pattern, 'tokens' ) ;
tokens = vertcat( tokens{:} ) ;
names = tokens(:,1) ;
data = str2double( tokens(:,2:3) ) ;
Using tokens is roughly the same as matching the normal way, you define a pattern that matches the full block that contains what you need to extract, but then you frame the parts that you want to be extracted specifically within () in the pattern. These parts are called tokens.
The pattern that I built here is based on the following observations:
- Parameter names are always separated from their surrounding by white spaces and they do not contain white spaces, hence the \S+ to match them.
- Values cannot be matched the same way, because there are cases where they touch the opening parenthesis associated with the error, so we can match them using [^\(]+ (one or more char that is not an opening parenthesis).
- What is within values and errors contain no numeric digit and symmetrical errors don't need a sign, so we can "eat the string" after the value as long as characters are not numeric digits, hence the \D+.
- Errors seem to be followed by a white space, so \S+ to get them.
With that, you get:
>> names
names =
7×1 cell array
{'Cell_C_ph1_pat1'}
{'Cell_A_ph1_pat1'}
{'Cell_B_ph1_pat1'}
{'X-tan_ph1_pat1' }
{'V-Cagl_ph1_pat1'}
{'W-Cagl_ph1_pat1'}
{'U-Cagl_ph1_pat1'}
>> data
data =
