Advanced Usage¶

Advanced techniques for using mp-units in sophisticated scenarios beyond standard quantity calculations.

Available Guides¶

Pure Dimensional Analysis - Use dimensions without specific units for symbolic computation, compile-time validation, and custom arithmetic types
Type-Safe Indices and Offsets - Model container indices and offsets as quantities with point origins, covering 0-based vs 1-based indexing, SI vs IEC element prefixes, and stride arithmetic
Decompose a Vector Quantity into Components - Split a vector quantity into named, strongly-typed 1D-vector component quantities, covering the quantity hierarchy, get<Idx>/get<QS>, structured bindings, and the representation requirements
Represent an Axial Vector as an Antisymmetric Tensor - Model a quantity the ISQ defines as a vector (e.g. angular velocity) as a skew-symmetric tensor in your own domain, bridged to isq::angular_velocity with an explicit hat/vee dual
Ensure Ultimate Safety - Combine constrained reps, constraint_violation_handler, and check_in_range for guaranteed bounds enforcement
Working With Nondimensionalized Physics - Use mp-units alongside natural units and dimensionless quantities, covering the complete scale-in/scale-out workflow and tradeoffs

Use these advanced techniques when you:

Need dimensional analysis without actual quantity values
Build symbolic computation or automatic differentiation systems
Validate dimensional consistency at compile-time
Work with template metaprogramming involving dimensions
Implement custom arithmetic types with dimensional correctness
Work in nondimensionalized or natural-unit systems and want to retain strong typing
