Hello list, I'm trying to calculate point-wise product from a MultiArray (basically the adjacency list from the boost graph). Can anybody suggest how the point-wise product can be calculated in boost in the most efficient way (of course i can implement the function myself with a nested for())? For those not familiar with point-wise product, it's defined as: A[i,j] = B[i,j] * C[i,j] TIA /CM -- Claudio Martella Digital Technologies Unit Research & Development - Analyst TIS innovation park Via Siemens 19 | Siemensstr. 19 39100 Bolzano | 39100 Bozen Tel. +39 0471 068 123 Fax +39 0471 068 129 claudio.martella@tis.bz.it http://www.tis.bz.it Short information regarding use of personal data.
