WebOct 9, 2016 · If all your matrices have the same sparsity pattern, then you can simply multiply the VAL array element-wise. There is probly no API function to do that, but it is very easy (just a for loop). In addition, you can "#pragma omp parallel for" the loop to gain a bit more. – BrunoLevy Oct 9, 2016 at 11:26 1 WebThe most general block operation in Eigen is called .block () . There are two versions, whose syntax is as follows: As always in Eigen, indices start at 0. Both versions can be used on fixed-size and dynamic-size matrices and arrays. These two expressions are semantically equivalent.
