Hello,
I'm currently trying to use Octave to analyze data taken with a photoacoustic
research device.
The device writes out data into a csv file, which can be read by Excel, or
LibreOffice. The waveform data however is placed in a single row, and can at
times consist of over 10k ADC readings, which leads to a line length at times
of over 72k characters.
The native csv2cell packaged in the io package cannot handle this.
When I modify a local version to have a MAXSTRINGLENGTH of 131072, I can read
the files I need to.
Since this value is only for a single character buffer allocation, why can't
this be set much larger by default?
