Bivariate atoms

Functions of two expression arguments.

Usage

sd_elementwise_mult(l, r)
sd_matmul(x, y)
sd_quad_over_lin(l, r)
sd_rel_entr(l, r)
sd_rel_entr_first_scalar(l, r)
sd_rel_entr_second_scalar(l, r)

An expression handle.

sd_elementwise_mult: elementwise (Hadamard) product.
sd_matmul: matrix product \(x y\).
sd_quad_over_lin: the quadratic-over-linear \(\lVert x \rVert^2 / y\).
sd_rel_entr: relative entropy \(x \log(x / y)\). Like 'sparsediffpy' make_rel_entr, it dispatches on operand size: a scalar l with a non-scalar r uses sd_rel_entr_first_scalar, the reverse uses sd_rel_entr_second_scalar, and otherwise it is elementwise.
sd_rel_entr_first_scalar, sd_rel_entr_second_scalar: relative entropy with a scalar first or second argument broadcast against the other.
