Parameter¶

class Parameter(name)[source]¶

Bases: qiskit.circuit.parameterexpression.ParameterExpression

Parameter Class for variable parameters.

Create a new named Parameter.

Parameters: name (str) – name of the Parameter, used for visual representation. This can be any unicode string, e.g. “ϕ”.

Methods

`arccos`	Arccos of a ParameterExpression
`arcsin`	Arcsin of a ParameterExpression
`arctan`	Arctan of a ParameterExpression
`assign`	Assign one parameter to a value, which can either be numeric or another parameter expression.
`bind`	Binds the provided set of parameters to their corresponding values.
`conjugate`	Return the conjugate.
`cos`	Cosine of a ParameterExpression
`exp`	Exponential of a ParameterExpression
`gradient`	Get the derivative of a parameter expression w.r.t.
`is_real`	Return whether the expression is real
`log`	Logarithm of a ParameterExpression
`sin`	Sine of a ParameterExpression
`subs`	Substitute self with the corresponding parameter in `parameter_map`.
`tan`	Tangent of a ParameterExpression
