Sorry if this is basic, but I cannot figure out how to do it in parallel and I'd rather not say how I do it in single-processor mode because I would be ashamed.
Say I have a matrix and I want to multiply a row times a vector to obtain a scalar. Actually I would like to choose some rows, multiply each of them by the vector and then add the scalars up. Or, conversely, sum all the rows colmunwise and then multiply the sum by a vector. How can I do this? Regards -- jeremy theler www.seamplex.com
