Evaluation and fitting along one axis of an N-dimensional tensor, writing into a caller-provided output view.

Method suffixes follow BLAS naming (d = f64, z = Complex<f64>): evaluate_nd_dz_to maps real coefficients to complex values.

Inputs may have any strided host layout (non-contiguous inputs are copied once). Outputs must be host-resident compact column-major views whose shape equals the input shape with axis dim replaced by the output extent.

Each method returns Ok(()) after writing the result to out. On an error nothing is written to out:

• Error::NotSupported if the fitter does not support this pair of types (the default implementations), or if out is not a compact column-major view;
• Error::AxisOutOfRange if dim is not an axis of the input;
• Error::ShapeMismatch of the input if it does not have basis_size (evaluate) or n_points (fit) along dim, and of the output if out does not have the shape of the input with n_points (evaluate) or basis_size (fit) along dim;
• Error::DecompositionFailed if a fit needs the singular value decomposition of the matrix and it fails.

An empty input of the right shape (a batch axis of extent 0) gives Ok(()) without computing anything.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
