Class Inheritance Diagram

Implement visitor to parsed fit terms expression that evaluates all terms.

class autowisp.fit_expression.evaluate_terms_visitor.EvaluateTermsVisitor(*data)

Bases: ProcessTermsVisitor

Visitor to parsed fit terms expression evaluating all terms.

__init__(*data)

Define the data used to evaluate the terms.

Parameters:

data (numpy structured array or asteval.Interpreter) – If array, should contain fields with all variables required by the terms in the expression. If interpreter should have all these variables in its a symbol table.

Returns:

None

_end_expansion()

Return the result of an expansion and clean-up.

_process_term_product(input_terms, term_powers=None)

Add to the current expansion the product of input terms to powers.

_start_expansion(num_output_terms, term_length, dtype)

Allocate the output array for an expannsion operation.

visitFit_term(ctx: Fit_termContext)

Evaluate the corresponding term.

visitFit_terms_expression(ctx: Fit_terms_expressionContext)

Return all terms defined by the term expression.
