Calling specific numbers from an non formatted text file in matlab

Question

I have a text file which consists:

// MATLAB to process this file
ModelName : Matlab1
PerturbationId : 0
X1X2_001 : 0.270971584968118
X1X2_002 : 0.55555
OBJECTF : ?
NumberOfRuns : 25
SimulationId : 0

What I want to do is to get 0.270971584968118 and 0.55555 out of it, the important thing is that the file is not the same after each run, I mean the name of X1X2 may change (but there is always 001 and 002 at the end). also the values may change (0.270971584968118 and 0.55555). I used textscan but since the file has not specific format (values are not separated by tab, and they are not tabular) it was not useful.

Thanks

if you read in the file and set delimiter to ":", you are looking at the 6th and 8th (or (3,2),(4,2)) th element. — GameOfThrows, Aug 14 '15 at 14:44

OKAY. So the straightforward way says:

%//read in file
fileID = fopen('your.txt')
C = textscan(fileID,'%s %s','Delimiter',':');  %// delimit on ':'
%//you are looking for C{2} the second row of the cell.
value1 = cell2mat(C{2}(4,:));
>> 0.270971584968118
value2 = cell2mat(C{2}(5,:));
>> 0.55555

So this is quite straight forward and easy to understand, but it is not the most efficient way. For efficiency, look for alternatives to cell2mat.
