npx skills add parcadei/Continuous-Claude-v3 --skill interpolation --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Interpolation ## When to Use Use this skill when working on interpolation problems in numerical methods. ## Decision Tree 1. **Assess Data Characteristics** - How many data points? Spacing uniform or non-uniform? - Is data smooth or noisy? - Need derivatives at endpoints? 2. **Select Interpolation Method** - Few points (<10): Polynomial (Lagrange, Newton) - Many points, smooth data: Cubic splines - Noisy data: Smoothing splines or least squares - High dimensions: Use simplex-based (n+1 neighbors vs 2^n) 3. **Implement with SciPy** - `scipy.interpolate.CubicSpline(x, y)` - natural cubic spline - `scipy.interpolate.make_interp_spline(x, y, k=3)` - B-spline - `scipy.interpolate.interp1d(x, y, kind='cubic')` - 1D interpolation 4. **Validate Results** - Check for Runge's phenomenon at boundaries (high-degree polynomials) - Cross-validate: leave-one-out error estimation - Visual inspection of interpolated curve - `sympy_compute.py limit "interp_error" --at boundaries` 5. **High-Dimensional Considerations** - Coxeter-Freudenthal-Kuhn triangulation for O(n log n) point location - Barycentric subdivision for balanced performance ## Tool Commands ### Scipy_Cubic_Spline ```bash uv run pytho

What does the interpolation skill do?
Problem-solving strategies for interpolation in numerical methods
How do I install it?
Run `npx skills add parcadei/Continuous-Claude-v3 --skill interpolation --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From parcadei/Continuous-Claude-v3, a repository with 3,879 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
