Right now, as I recall, the function pdl() can process different kinds of arguments. You can pass it (1) a piddle, which it copies, or (2) an array reference, which it converts into a piddle, or (3) a collection of scalars, which it converts to a piddle. It seems like you are suggesting modifying the pdl() function to also handle string arguments which has a matlab formatted array, or for that matter formatted like PDL stringifies piddles. Is that correct? If so, I'm with Maggie. I think it's a great idea. It may be a bit tricky differentiating between a single scalar argument passed to pdl() vs a string containing an array, but that's still a very doable task. At this point we'll need to have the code written, tests written, and documentation written. Do you have any tuits for this? I'd be happy to help with any of those pieces. David
