EigenAllocator allocates and populates the input to the
matrix eigendecomposition dense matrix kernel for the purposes of conducting
a single performance trial with the EigenMicrobenchmark function. The
matrices or vectors corresponding to the index parameter must be
allocated, initialized and returned in the kernelParameters list.EigenAllocator(benchmarkParameters, index)DenseMatrixMicrobenchmark specifying various parameters
