Re: [Bug-apl] take and drop on matrixes?

[Blake McBride]

GNU APL is APL.  2↑MATRIX is not.

Thanks, it looks indeed like I have to specify all sizes in GNU APL.

Hi Alexey,

I believe you are using a Dyalog-specific feature.

Try  2 2↑XG1 instead.

Hi list

The following code with given matrix XG1 produces an error in GNU APL on attempt to take or drop rows:

      XG1
1 9 5 3 6
5 4 8 2 3
7 7 6 2 6
      ⍴XG1
3 5
      2↑XG1
RANK ERROR
      2↑XG1
      ^ ^
      2↓XG1
RANK ERROR
      2↓XG1
      ^ ^

However this works fine on Dyalog APL:
      2↑XG1
1 9 5 3 6
5 4 8 2 3

Is where some incompatibilities with a standard?
