描述

I only started using breeze a few hours ago so I may be wrong on this.

I tried to load a space separated file but I could only specify one character as a separator. Unfortunately, my dataset's separator is not consistent(2-4 spaces) as are many other datasets. Wouldn't it be better if the separator is a regular expression? That way I can specify separators like: csvread(file, "\\s+") or csvread(file, ",\\s?")

With regards to csvwrite, I may want to use a comma followed by a space.

Cheers

研究方向
Locate the csvread and csvwrite functions in the Breeze library, likely in the `breeze.linalg.csv` package or similar. Examine how the separator parameter is currently used (single character) and modify the signature to accept a regex string or pattern. Update the parsing logic to split lines using the regex. Consider backward compatibility by allowing both char and regex inputs. Check existing tests and examples to ensure correctness.
