Hope it will eventually make it to the parallel package, once its stability is proved. | Hope it will eventually make it to the parallel package, once its stability is proved. | ||

There is an overhead for parallelization. Hence this package is not suited for very fast functions. | |||

The following sample code was an answer to [http://stackoverflow.com/questions/27422219/for-every-row-reshape-and-calculate-eigenvectors-in-a-vectorized-way this question]. The goal was to diagonalize 2x2 matrices contained as rows of a 2d array (each row of the array being a flattened 2x2 matrix). | The following sample code was an answer to [http://stackoverflow.com/questions/27422219/for-every-row-reshape-and-calculate-eigenvectors-in-a-vectorized-way this question]. The goal was to diagonalize matrices. For this example, 2x2 matrices contained as rows of a 2d array (each row of the array being a flattened 2x2 matrix). Note that in this case the function is too fast, so the performance penalty is too high to gain anything. | ||
