Field Documentation

scs_int ed

number of dual exponential cone triples $(n_{\mathrm{de}})$

See Also

primal exponential cone

scs_int ep

Number of primal exponential cone triples $(n_{\mathrm{ep}})$.

See Also

dual exponential cone

scs_int f

Number of linear equality constraints $(n_{\mathrm{f}})$.

The corresponding cone is the zero-cone $\mathcal{K}^{f}_{n_f} = \{0_{n_f}\}$

scs_int l

Dimension of LP cone $(n_{\mathrm{l}})$.

This is used to specify element-wise inequalities.

The corresponding cone is the positive orthant $\mathcal{K}^{l}_{n_l} = \{x\in\mathbb{R}^{n_l}: x_i \geq 0, \forall i\}$

scs_float* p

Array of power cone params $(\alpha_1,\ldots,\alpha_{N_{\mathrm{p}}})$.

Note

Cone parameters must be in $[-1, 1]$.

Negative values are interpreted as specifying the dual cone

scs_int psize

Number of (primal and dual) power cone tuples $(N_{\mathrm{p}})$.

scs_int* RESTRICT q

Array of SOC constraints $(n_{\mathrm{q},1},\ldots, n_{\mathrm{q},N_{\mathrm{q}}})$.

This is the Cartesian product of $N_{so}$ cones with dimensions $n_{so_1},\ldots, n_{so,N_{so}}$.

This array contains the dimensions $(n_{so_1},\ldots, n_{so,N_{so}})$.

The length of this array is specified in qsize.

See Also

number of second-order cones

scs_int qsize

Length of SOC array, i.e., number of second-order cones $(N_{\mathrm{q}})$.

See Also

array of second-order cones

scs_int* RESTRICT s

array of PSD constraints $(k_1,\ldots, k_{N_{\mathrm{s}}})$

Array of dimensions of PSD constraints.

See Also

number of PSD cones

scs_int ssize

length of PSD array $(N_{\mathrm{s}})$

See Also

array of positive semidefinite cones
