SparseMatrixVectorMicrobenchmark {RHPCBenchmark} | R Documentation |
SparseMatrixVectorMicrobenchmark
conducts a single performance trial
of the matrix-vector multiplication sparse matrix kernel for the matrix given
in the kernelParameters
parameter. The function times the single
function call kernelParameters$A %*% kernelParameters$b
.
SparseMatrixVectorMicrobenchmark(benchmarkParameters, kernelParameters)
benchmarkParameters |
an object of type

kernelParameters |
a list of matrices or vectors to be used as input to the sparse matrix kernel |
a vector containing the user, system, and elapsed performance timings in that order
