plot_variance

pyoof.plot_variance(matrix, order, diag, cbtitle, title)

Variance-Covariance matrix or Correlation matrix figure. It returns the triangle figure with a color amplitude value for each element. Used to check/compare the correlation between the fitted parameters in a least squares minimization.

Parameters:

matrix : ndarray

Two dimensional array containing the Variance-Covariance or Correlation function. Output from the fit procedure.

order : int

Order used for the Zernike circle polynomial, \(n\).

diag : bool

If True it will plot the matrix diagonal.

cbtitle : str

Color bar title.

title : str

Figure title.

Returns:

fig : Figure

Triangle figure representing Variance-Covariance or Correlation matrix.
