core/mathematical_expression-0.1.0#

Schema that describes a mathematical_expression.

Description

Defines a mathematical expression using sympy syntax. https://docs.sympy.org/latest/modules/core.html#module-sympy.core.sympify

Also contains any predefined (constant) parameters used in the expression.

Outline

Schema Definitions

This type is an object with the following properties:
  • expression
    stringRequired
    A string representation of the mathematical expression. The expression must conform to the sympy syntax.

    No length restriction
  • parameters
    object
    List of constant parameters that to be set in the mathematical expression.

    object

Examples

A linear mathematical expression:

!<asdf://weldx.bam.de/weldx/tags/core/mathematical_expression-0.1.0>
  expression: a*x + b
  parameters:
    a: !<asdf://weldx.bam.de/weldx/tags/units/quantity-0.1.0> {value: 1.2, units: !<asdf://weldx.bam.de/weldx/tags/units/units-0.1.0> volt}
    b: !<asdf://weldx.bam.de/weldx/tags/units/quantity-0.1.0> {value: 3.4, units: !<asdf://weldx.bam.de/weldx/tags/units/units-0.1.0> volt}
