Module fitters 

Fitters for least-squares problems with various matrix types

This module provides fitters for solving min ||A * coeffs - values||^2 where the matrix A and value types can vary:

• [RealMatrixFitter]: Real matrix A ∈ R^{n×m}
• [ComplexToRealFitter]: Complex matrix A ∈ C^{n×m}, real coefficients
• [ComplexMatrixFitter]: Complex matrix A ∈ C^{n×m}, complex coefficients
