I have some data stored in a .cnv file, the data is stored as follows:
# <!-- Pressure voltage, Pressure, Strain Gauge -->
# name 0 = prSM: Pressure, Strain Gauge [db]
# name 1 = sal00: Salinity, Practical [PSU]
# name 2 = t090C: Temperature [ITS-90, deg C]
# datcnv_skipover = 0
# file_type = ascii
*END*
-0.051 0.0312 15.4328
-0.061 0.0512 15.4448
Here we have some text at the top of the .cnv file and the data stored after the string END. Each column of the data is described by name 0 for column 1, name 2 for column 1, and so on... How could I extract these names i.e. create a variable named prSM, sal00, t090C respectively? The first hurdle is to extract the variable names, I can worry about extracting the data later. Many thanks.

fid = fopen('yourfile.cnv');
line1 = fgetl(fid);
res=line1;
while ischar(line1)
line1 = fgetl(fid);
res =char(res,line1)
end
fclose(fid);
for k=2:4;
idx1=regexp(res(k,:),'=')
idx2=regexp(res(k,:),':')
name{k-1}=res(k,idx1+1:idx2-1)
end

You've specified k = 2:4, I'm guessing this wont work for my actual data, as there are 100+ lines of text above the first line specified above, thus I was hoping of a method that used 'name0', 'name1' etc to obtain the variable name...

then use for k=2:100
the names are: name{1}, name{2},... .. It's better then name1 name2 ..
