I'm having a problem with dlmread where I'm specifying a range for it to read a csv file and it reads beyond that range.
My data looks like this: Date,Time,Intensity (mm/h),Precipitation since start (mm),Radar reflectivity (dBz),Number of detected particles,Temperature in sensor (°C),Spectrum 21.09.2012,14:34:00,0.000,0.00,-9.999,0,23,<SPECTRUM>ZERO</SPECTRUM>
My code looks like: rowcolrange = [1 2 1 6]; spdshtrange = 'C2..G2'; delimiter = ','; data = dlmread(filepathandname,delimiter,rowcolrange);
The error looks like this: ??? Error using ==> dlmread at 145 Mismatch between file and format string. Trouble reading number from file (row 1, field 8) ==> <SPEC
So it's trying to read the 8th field when I specify it not too. Why is this? Any help would be great!

everything in the file must be numeric for you to be able to use dlmread, even if the non-numeric data is in a column you are not trying to read.
You should be using textscan()
