Approximation

Basic, Professional, Developer Suite

Approximates a linear model Y(X) to given data according to the method of the least square error.

Approximation2D

Basic, Professional, Developer Suite

Approximates a linear model Y(X, Z) with two independent variables to given 2D data according to the method of the least square error.

LeastSquaresCircle

Professional, Developer Suite

Calculates the least squares circle (LSCI) of a two-dimensional point set (least squares reference circle). Used to determine roundness.

MaximumInscribedCircle

Professional, Developer Suite

Calculates the maximum inscribed circle (MICI) of a two-dimensional point set. Used to determine roundness.

MinimumCircumscribedCircle

Professional, Developer Suite

Calculates the minimum circumscribed circle (MCCI) of a two-dimensional point set. Used to determine roundness.

MinimumZoneCircle

Professional, Developer Suite

Calculates the reference circles of the minimum zone (MZCI) of a two-dimensional point set. Used to determine roundness.

NonLinCurveFit

Basic, Professional, Developer Suite

Approximates a non-linear model to a data set and returns the model parameters found, the modeled data and a large number of statistical results.

NonLinModel

Basic, Professional, Developer Suite

Calculates a non-linear model function for model parameters that you specify.

ParameterEstimation

Basic, Professional, Developer Suite

Approximates a non-linear model to a data set. Here, non-iterative methods are used. The Grid Search and the Random Search methods are the options available.
