Hello everybody,

I have a text-file which looks like this:

....

$ S3/460

SCHMIERSTOFFART = Polyglykol_1:1
NUE40 = 460
NUE100 = 82
RHO15 = 1.05

$ S7-150

SCHMIERSTOFFART = Polyglykol
SCHMIERSTOFFBEZEICHNUNG = FVA522 S7 Grundoel
NUE40 = 131
NUE100 = 21
RHO15 = 0.9943
....

The String after each $ represents the name of the oil. Now my question:

I need to extract the names of the oils (e.g. "S3/460" and "S7-150") into a cell array.

Can anybody help me, please?

Thanks!

If the only time a $ appears in the file is immediately before an oil name,
then this might work:

fid = fopen('myfile.txt');
oils = textscan(fid, '%*[^$] %*c %s');
fclose(fid);

In this case, %*[^$] skips everything that is not a $, %c skips the $, and
%s captures the oil name.
