How best to form a matrix from a list of noun names where each noun is a list of values that will form a column in the matrix?
Below is one solution, are there better ones?
Named nouns:
'Var3 Var5 Var4 Var1 Var2' =: 5 7 ?.@$ 60
evoke=: 3 : 'y~'
toMatrix =: [: ,.&:>/ [: evoke&.> ;:
toMatrix 'Var1 Var2 Var3 Var4 Var5'
