void setCoefA(const Field2D &val)

Set coefficients for inversion. Re-builds matrices if necessary.

void setCoefC(const Field2D &val)

void setCoefD(const Field2D &val)

void setCoefEx(const Field2D &val)

void setCoefEz(const Field2D &val)

FieldPerp solve(const FieldPerp &b)

FieldPerp solve(const FieldPerp &b, const FieldPerp &x0)

Solve Ax=b for x given b

This function will

1. Take the fourier transform of the y-slice given in the input
2. For each fourier mode a) Set up the tridiagonal matrix b) Call the solver which inverts the matrix Ax_mode = b_mode
3. Collect all the modes in a 2D array
4. Back transform the y-slice

Input:

Return

The inverted variable.

Parameters

• b: A 2D variable that will be fourier decomposed, each fourier mode of this variable is going to be the right hand side of the equation Ax = b
• x0: Variable used to set BC (if the right flags are set, see the user manual)
