Module KeyedMatrix

source code

Classes for matrices with symbolic indices (i.e., Key objects)

Classes

[hide private]

KeyedMatrix
A dictionary-based representation of a two-dimensional matrix

DynamicsMatrix
Matrix subclass that provides some structure to be exploited for greater user friendliness

IncrementMatrix
A matrix for incrementing/decrementing the value of a given feature by a constant amount

ScaleMatrix
A matrix for incrementing/decrementing the value of a given feature by some percentage of another feature (possibly the same one)

SetToConstantMatrix
A matrix for setting the value of a given feature to a specified constant value

SetToFeatureMatrix
A matrix for setting the value of a given feature to a specified percentage of some other feature

ActionCountMatrix
A matrix for setting the value of a given feature to a count of a certain type of action

IdentityMatrix
A matrix for leaving the value of a given feature unchanged

getDynamicsTypes()

source code

Automatic extraction of possible DynamicsMatrix subclasses

Returns: dict:str->class: all available subclasses of DynamicsMatrix

makeIdentityMatrix(keys)

source code

Generates an identity matrix, M, over the set of keys. This matrix is filled and frozen.

Parameters:

keys (Key[]) - the keys of the vector, v, for which we want M*v=v

Returns: KeyedMatrix
