A[index1d(x,y,z)] = A[index1d(x,y,z)] + B[i]*W;
in C/C++
Presuming conformance of dimensions, etc.,
A(index1d(x,y,z)) = A(index1d(x,y,z)) + B(i)*W;
in MATLAB replacing the braces.

Since C++ is 0-based indexing and MATLAB is 1-based indexing, you will probably need to add 1 to your indexes in the above conversion, either explicitly or as part of upstream code.

James -- good catch! I meant to add that caveat as well but forgot...it can be a real bugger to convert if forget or depending just how indices were used...
