Field theoretic simulator (base class).
The Simulator base class provides tools needed in field-theoretic simulations that are based on a partial saddle-point approximation, including field theoretic Monte Carlo and field-theoretic Langevin simulations. Subclasses of this class provide algorithms and more specialized data structures needed by specific sampling methods.
The analyzeChi() function constructs and diagonalizes the projected chi matrix. This is a singular nMonomer x nMonomer matrix defined by evaluating the projection of the chi matrix into the subspace of fluctuations that preserves total monomer concentration. The eigenvalues and eigenvectors of this matrix via the chiEvals and chiEvecs functions, respectively.
The functions computeWc, computeCc and computeDc compute components components of various types of multi-component fields (i.e., fields that are associated with a monomer type index) in a basis of eigenvectors of the projected chi matrix. Names such as wc, cc and dc that end with a suffix "c" refer to components of multi-component fields that are defined using this eigenvector basis.

Get an array of the eigenvalues of the projected chi matrix.
The projected chi matrix is given by the matrix product P*chi*P, where P is the symmetric projection matrix that projects onto the subspace orthogonal to the vector e = (1,1,...,1). The projected chi matrix is singular, and has a zero eigenvalue with associated eigenvector e. By convention, this zero eigenvalue and its eigenvector e are listed last, with index nMonomer - 1.

Get the matrix of all eigenvectors of the projected chi matrix.
This function returns the entire nMonomer x nMonomer matrix of the eigenvectors of the projected chi matrix, in which each row is an eigenvector. The first (row) index of this matrix thus identifies an eigenvector, while the second (column) index identifies the monomer type associated with one component of an eigen-vector.
Each eigenvector is normalized such that the sum of the squares of its elements is equal to nMonomer, the number of monomer types. The sign of each vector is chosen so as to make the first (0) component non-negative. The last eigenvector is always the null vector e = (1,1,...,1).
For the case nMonomer = 2 of an AB system, the resulting two eigenvectors are (1,-1) and (1,1).

Compute eigenvector components of the current w fields.
Compute and store the components of the values of the w fields on nodes of a real-space grid (r-grid) in a basis of the eigenvectors of the projected chi matrix. The component field \( W_{a}({\bf r}) \) at grid point \( {\bf r} \) is given using Einstein summation by
\[ W_{a}({\bf r}) = v_{ai} w_{i}({\bf r}) / M \]
where \( w_{i}({\bf r}) \) is the w-field associated with monomer type \( i \), \( v_{ai} \) is eigenvector a of the projected chi matrix, and M = nMonomer.

Get all eigenvector components of the current c fields.
Each component \(C_{a}({\bf r}) \) is a point-wise projection of the monomer c fields onto a corresponding eigenvector of the projected chi matrix. The resulting value \( C_{a}({\bf r}) \) for eigen-component a at grid point \( {\bf r} \) is given using Einstein notation as
\[ C_{a}({\bf r}) = v_{ai} c_{i}({\bf r}) \]
where \( c_{i}({\bf r}) \) is the concentration / volume fraction field associated with monomer type i.
Note: The above definition \( C_{a} \) uses a different prefactor than that used to define the corresponding w-field component \( W_{a} \) given in the documentation of the function wc(), without the prefactor of 1/nMonomer. This is intentional, and is convenient for other aspects of the underlying theory.
