Calculate the product of X by Q raised to any power
spde.eval(G, Gcols=NA, Gvals=NA, TildeC, Lambda, Blin, x, power = -0.5)
G,Gcols,Gvals |
If Grows (first argument) is a sparse matrix (from 'Matrix' package), then the following arguments ('Gcols', 'Gvals') are useless. Three arrays (same dimension) which provide respectively the row, the column indices, as well as the value for the corresponding cell element. |
TildeC |
The TildeC vector (same dimension as the G matrix above) |
Lambda |
The scaling Lambda vector (same dimension as the G matrix above) |
Blin |
The set of Blin coefficients |
x |
The vector to be operated (same dimension as the G matrix above) |
power |
Power of the matrix |
The solution vector
