•UIndicesSupply

A small illustration of how UIndicesSupply works:

NM[UMatrix[a] + q, UMatrix[b] + UMatrix[c], UMatrix[d], r]

(q + a) '6 (b + c) '6 d '6 r

UIndicesSupply[UVector[v] . % . UVector[w]]

v(n _ 1) '6 (q + a(n _ 1, n _ 2)) '6 (b(n _ 2, n _ 3) + c(n _ 2, n _ 3)) '6 d(n _ 3, n _ 4) '6 r '6 w(n _ 4)

UIndicesCounter = 0 ;

UIndicesSupply[UTrace[%%%]]

(q + a(n _ 1, n _ 2)) '6 (b(n _ 2, n _ 3) + c(n _ 2, n _ 3)) '6 d(n _ 3, n _ 1) '6 r
