Constructor & Destructor Documentation

PWConstCoefficient::PWConstCoefficient

(

int

NumOfSubD = 0

)

[inline, explicit]

Constructs a piecewise constant coefficient in NumOfSubD subdomains.

Definition at line 55 of file coefficient.hpp.

References constants.

PWConstCoefficient::PWConstCoefficient

(

Vector &

c

)

[inline]

c should be a vector defined by attributes, so for region with attribute i c[i] is the coefficient in that region

Definition at line 60 of file coefficient.hpp.

References constants, Vector::SetSize(), and Vector::Size().
