vec_ops
Matrix operations used by the L-BFGS algorithm.
Functions
| difference_and_save | Calculates the difference of two slices and saves it in the third: out = a - b |
| inner_product | Calculate the inner product of two slices |
| inplace_vec_add | Calculates out = out + s * a |
| norm1 | Calculate the 1-norm of a slice |
| norm2_sq | Calculate the squared 2-norm of a slice |
| norm2 | Calculate the 2-norm of a slice |
| norm_inf | Calculate the infinity-norm of a slice |
| scalar_mult | Calculates a scalar times slice: out = s * out |
