To zero out the small elements whose absolute values are smaller than a given criterion.
To zero out the small elements in A whose absolute values are smaller than a given criterion, specified by small_cri. By default, small_cri=eps. Due to operations on floating point numbers, many quantities should be zero mathematically but are actually not. If these "fuzzy" quantities are carried over in further calculations, erroneous results may arise. They will also unnecessarily increase the number of non-zero elements in sparse matrices and slow down the calculations.
