hi, i need to speed code but i see can't possible to use vector to find

element in matrix

code:

R is a matrix (x,2)

Ntrades,NtTR are matrix(n,m)

for gg=1:rows(R)

[roww(gg,1),coll(gg,2)]=find(Ntrades(1:R(gg,1),R(gg,2))<=NTR(R(gg,1),R(gg,2)))(end);

endfor

it's possible to velocize it? thank for help
