Hi Bug APL,
I found a paper that computes eigenvalues using the following equation
eig←{t[;⍒(t←⍂⍵)[0;]]}
where ⍵ is a matrix of coefficients.
It looks like the symbols are in the unicode standard, but I have never seen a definition before:
⍁ | U+2341 | ⌼ | APL Functional Symbol Quad Slash |
⍂ | U+2342 | ⍂ | APL Functional Symbol Quad Backslash |
