File I/O for Cell Arrays

Wrappers for reading and writing text between files and cell arrays.

Provides simple I/O routines, file2cell and cell2file, for reading an ASCII text file to a cell array of strings (one line per cell element) and writing a cell array of strings (columnwise) to an ASCII file, respectively. The routines can be easily extended with regular expressions to add extra functionality, f.e., to remove empty lines, etc.
