I have a file name named Lek0_ServoU_C20_R40_PS8_14mei_1746.log, and want to put these parameters into a matrix with some values which come out of our first script. Is there an option that matlab reads this information out of the title from the file? So that we get a table with the column Lek, C and R and the different parameters underneath it?

Hi Suzan,

You can try using textscan to read data from the filename. It will be most straighforward if your filenames are consistent, for example:

files=dir('*.log');
leks=NaN(length(files),1);
Cs=leks;
Rs=leks;
for i=1:length(files)
    out=textscan(files(i).name,'Lek%f_ServoU_C%f_R%f')
    leks(i)=out{1};
    Cs(i)=out{2};
    Rs(i)=out{3};
end
T=table(leks,Cs,Rs,'VariableNames',{'Lek','C','R'});
