Constrains \(\|X_i\|_2 \le t_i\) for each column or row \(i\),
where t is a vector and X is a matrix.
SOC(t, X, axis = 2L, constr_id = NULL)An SOC constraint object.
A CVXR expression (scalar or vector) representing the upper bound.
A CVXR expression (vector or matrix) whose columns/rows are bounded.
Integer, 2 (default, column-wise) or 1 (row-wise). Determines whether columns (2)
or rows (1) of X define the individual cones.
Optional integer constraint ID.
