Delta

Uncertainty symbolic and numeric calculator

“Delta” is a function dedicated to the symbolic and numeric calculations of uncertainties. The uncertainty calculation is based on the symbolic evaluation of the partial derivatives of the function defined by user. The norm of uncertainty vector, obtained by weighting the variables uncertainties by their partial derivatives, can be performed with:
- L1-norm : sum of absolute distances, also known as "Manhattan" or "city blocks"
- L2-norm : Euclidean norm
The results in terms of value, uncertainty and partial derivatives can be displayed in MATLAB console or saved in specific numeric and symbolic variables.
