-Creates the cone of real or complex Hermitian positive semidefinite matrices. The entries of the upper-triangular part of matrix `X` are stored in the vector `x` of dimension `dim`.
-A ``r \\times r`` real matrix has ``r(r+1)/2`` upper triangular elements and results in a vector of ``\\mathrm{dim} = r(r+1)/2``. A ``r \\times r`` complex matrix has ``r^2`` upper triangular elements and results in a vector of ``\\mathrm{dim} = r^2``.
