aspcore.matrices_jax.regularize_matrix_with_condition_number(mat, max_cond=10000000000.0)

Adds a scaled identity matrix to the matrix in order to ensure a maximum condition number

Parameters:

• mat (ndarray of shape (a, a)) – Matrix to be regularized

• max_cond (float, optional) – maximum condition number allowed. Must be positive. The default is 1e10.

Returns:

mat_reg – Regularized matrix

Return type:

ndarray of shape (a, a)
