Functions in FixedPoint (0.6.3)

PolynomialExtrapolation

PolynomialExtrapolation This function performs Minimal Polynomial extrapolation (MPE) or Reduced Rank Extrapolation (RRE) given a matrix of previous iterates of the function.

PutTogetherIteratesWithoutJumps

PutTogetherIteratesWithoutJumps This function takes the previous inputs and outputs and assembles a matrix with both excluding jumps.

EpsilonExtrapolationVectorOfInverses

EpsilonExtrapolationVectorOfInverses This is a helper function for EpsilonExtrapolation

EpsilonExtrapolation

EpsilonExtrapolation This function takes a matrix with previous iterates and extrapolates the limit of the sequence.

FixedPointNewInput

FixedPointNewInput This function takes the previous inputs and outputs from the FixedPoint function and determines what vector to try next in seeking a fixed point.

A function for plotting the convergence change over a series of iterates.

A function for finding the fixed point of a contraction mapping

ChangePerIterate

ChangePerIterate A function for plotting the change in each vector per iterate.
