SPDverif

Symmetric Positive Definite Stiffness Matrix Verificator

Syntax

SPDverif(K0, cDOFasc, K)

Parameters

INPUT ARGUMENTS:

K0:

Complete stiffness matrix of the structure [DOFn*nn x DOFn*nn]

K:

Active stiffness matrix of the structure (reduced to active DOF) [DOFn*nn-cDOF x DOFn*nn-cDOF]

cDOFasc:

Constrained degrees of freedom vector (ascending order) [cDOF x 1]

Examples

// Demo:
exec(atomsGetInstalledPath(["CEMEF-UTN" "1.1.6"]) + "/demos/HVtower.dem.sce", -1);
// Press the "View-code" menu to see the detailled code.
