You pass the filename, delimiter (ie. comma), ty is an array of ones(numeric types) and zeros (strings). Range is an optional 1x4 array of row_start, column_start, row_end, column_end. skip_last_delim is optional and will skip the last delimiter in case you produced your csv with a fprintf('%f,',x) statement and have an extra comma on your line.
dlmreadall accepts an array of size 1xN with 1's if the column is numeric and 0's where they are not.
It returns a cellstr populated by the delimited file.
This routine reads line-by-line so the only memory constraints are due to the cellstr, not the file.
