What's the paper? Does it say which APL they were using?

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
&#x233C;
APL Functional Symbol Quad Slash
⍂
U+2342
&#x2342;
APL Functional Symbol Quad Backslash
