Spectrahedron-class {volesti} | R Documentation |
An R class to represent a Spectrahedron
Description
A spectrahedron is a convex body defined by a linear matrix inequality of the form .
The matrices
are symmetric
real matrices and
denoted negative semidefiniteness.
Details
- matrices
A List that contains the matrices
.
Examples
A0 = matrix(c(-1,0,0,0,-2,1,0,1,-2), nrow=3, ncol=3, byrow = TRUE)
A1 = matrix(c(-1,0,0,0,0,1,0,1,0), nrow=3, ncol=3, byrow = TRUE)
A2 = matrix(c(0,0,-1,0,0,0,-1,0,0), nrow=3, ncol=3, byrow = TRUE)
lmi = list(A0, A1, A2)
S = Spectrahedron(matrices = lmi);
