Print format is vertical ordering? about ndarray-show HOT 11 OPEN

Should the 1d view also be vertical or remain horizontal?

from ndarray-show.

yes, 1d remains horizontal, thanks

This indeed seems surprising/counterintuitive if you're working with ndarrays as matrices. I think it'd be best to increment a major version and swap the default order. I only see two dependants (crunch-js, ndarray-ldl-factorization), so hopefully it won't have a large effect, but I'm new here so not 100% confident.

@mikolalysenko @Planeshifter — I never show a matrix without first transposing. @indiejoseph has a fork that transposes the output. Does anyone support merging this? Otherwise I will create:

1. A module that outputs the array in parsable format, à la numpy (effectively includes transposing, I think)
2. Another module that mixes this method into ndarray's prototype for you so that, if you desire, console.log(A) is parsable js that reconstructs the array (though perhaps without a guarantee of being trailing-bit-perfect)

from ndarray-show.

I think reworking the order seems reasonable if we increment the major version. The default version should aim to be as intuitive as possible for common cases, and you can always get whatever other order you like by calling ndarray.transpose()

Agreed. Okay. What about output formatting? Do you think aiming for parsable output is a worthwhile goal?

from ndarray-show.

Easily parseable output would be nice, but not at the expense of human readability.

Oops. Nope. I can dig a little more, but doesn't currently appear possible to extend the ndarray prototype, so I'll probably forget about that module. nbd. Probably for the best. console.log(show(A)) isn't much worse than console.log(A).

+1 The output of 2d-arrays currently does not adhere to the usual mathematical notation. Please transpose it! I agree that outputting 1d-arrays as a row makes sense in terms of screen space, but then at least you should add a ^T or similar in the end.

Sorry I've been slow on this! Was debating inside my head what the best variation is. I've just been using:

function show(label,data) {
  if( typeof data === 'number' ) { 
    console.log(label+' = '+data)
  } else if( data.dimension === 1 ) { 
    console.log(label+' = '+ndshow(data))
  } else {
    console.log(label+' =\n'+ndshow(data.transpose(1,0))+'\n')
  }
}

Since most of the time I'm just trying to dump a matrix scalar/vector/matrix to the screen. I also wanted to add formatting configuration and maybe the output = valid input feature. (Edit: uses fixed width float; already has precision)

from ndarray-show.

(not that that should go into the module; only that it's what I'm usually really after.)
