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
