SPDsolve

Solve symmetric positive definite system from CEMEF-UTN

Calling Sequence

[u0, u, P0] = SPDsolve(K0, K, P, cDOF, cDOFasc, nn)

Parameters

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]

P:

Nodal external loads vector (reduced to active DOF) [DOFn*nn-cDOF x 1]

cDOF:

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

cDOFasc:

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

nn:

Number of nodes [1 x 1]

OUTPUT ARGUMENTS:

u0:

Complete nodal displacements vector [DOFn*nn x 1]

u:

Active nodal displacements vector (reduced to active DOF) [DOFn*nn-cDOF x 1]

P0:

Complete nodal loads vector [DOFn*nn x 1]
