pvPacks¶
Purpose¶
Packs symmetric matrix into a structure of type PV.
Format¶
-
p1 =
pvPacks(p1, x, nm)¶ - Parameters
p1 (struct) – an instance of structure of type
PVx (MxM symmetric matrix) – data
nm (string) – matrix name.
- Returns
p1 (struct) – instance of
PVstruct.
Examples¶
struct PV p1;
p1 = pvCreate;
x = { 1 2,
2 1 };
p1 = pvPacks(p1, x, "A");
p1 = pvPacks(p1, eye(2), "I");
These matrices can be extracted using the pvUnpack() command:
print pvUnpack(p1, "A");
1.000 2.000
2.000 1.000
print pvUnpack(p1, "I");
1.000 0.000
0.000 1.000
