[Gretl-devel] matrix to list conversion

Hello, this time no bug report but a feature request. I think there is a pretty obvious feature that's missing and that's enabling conversion from matrices to lists, to facilitate roundtripping list - matrix - list. What I have in mind is something like this workaround: <hansl> function list mat2list(matrix inmat) list lout = null # initialize loop i=1..cols(inmat) series stemp = inmat[,i] list lout += stemp endloop return lout end function </hansl> For the direction list-to-matrix we have the wonderful {} syntax, and section 15.9 describes how to do matrix-to-series. So why not matrix-to-list? The thing is that currently lists and matrices in gretl are complementary; you cannot use matrices in estimation commands for example, and you cannot apply many calculations to lists. So I think we need to ensure quick and easy conversion from one type to the other. In terms of syntax, I wouldn't mind an explicit function like mat2list() above, to be built-in. What do you think? thanks, sven
