Hi,
I was wondering if this was written correctly (I use mathematica 4.1):
error1 = (-2/If[i < j, Sum[d3D[[i, j]], {i, 26}, {j, 26}]])*(If[j â? p,
Sum[ ((d3D[[i, j]] - d2D[[i, j]])/(d3D[[i, j]]*d2D[[i,
j]]))*(w[[i,
1]] - w[[i, 2]]), {i, 26}, {j, 26}]])
where d3D and d2D are matrices and w[i,2] and [wi,1] are vectors.
Everything has been declared.
Thanks
Rebeca
