Linear interpolation:calculate

Interpolation is an educational numerical analysis app focused on piecewise linear interpolation.
Enter your x and y data, provide the target x value, and quickly get: • the estimated f(x) value, • the segment formula used for the result, • a clear chart with known points and the evaluated point.
Key features: • Easy data input (commas or semicolons), • Built-in examples to get started quickly, • Fast piecewise linear interpolation calculation, • Local segment formula display (affine segment), • Lagrange polynomial display (depending on point set), • Visual chart rendering of results, • Chart image export (share and save to gallery).
Use cases: • Learning and practicing numerical methods, • Quick exercise checking, • Sharing visual results in class or study groups.
Important: • This app is intended for learning and calculation assistance. • Always verify results before academic or professional use. • Some features may require system permissions (e.g., gallery access to save images). • The app may contain ads.
