文摘
- •
We propose a new tool for vector field uncertainty analysis.
- •
It is based on the Helmholtz–Hodge decomposition.
- •
It uses the curl-free and divergence-free orthogonal components for uncertainty investigation.
- •
It uses a rank correlation coefficient to quantify the contribution of each component to the total uncertainty.
