## Description

Exact fraction arithmetic, not floating point. Determinants, inverses, eigenvalues and equation solving up to 20x20 — entirely offline.

Matrix Analysis computes exactly.

Most calculators work in floating point, so the determinant of a whole-number matrix comes back as 23.000000000000004 and an inverse arrives full of rounding noise. This one uses exact fraction arithmetic throughout. Integer matrices give integer answers. Inverses come back as fractions like -3/7, not 0.428571...

WHAT IT DOES

• Determinant, exactly, for matrices up to 20x20
• Inverse and adjugate, as exact fractions
• Minors and cofactors
• Rank, nullity, trace, transpose and reduced row echelon form
• Matrix multiplication
• Eigenvalues and eigenvectors, with the characteristic polynomial

SOLVING SYSTEMS

Type equations the way you write them:

    2x + 3y - z = 5
    x - y + 2z = 3
    3x + y + z = 10

Matrix Analysis builds the system and solves it, answering with your own variable names. It handles every case, not just the tidy one: a unique solution, infinitely many (shown as a particular solution plus a basis of the null space), or none at all — where it tells you the system is inconsistent and why. More unknowns than equations, or more equations than unknowns, both work.

EIGENVALUES DONE HONESTLY

The characteristic polynomial is computed exactly. Its roots are found numerically, then each one is offered a nearby exact value — so an integer matrix with integer eigenvalues gives exact answers and clean whole-number eigenvectors, while irrational and complex eigenvalues are shown as decimals and clearly marked approximate. You always know which you are looking at. Algebraic and geometric multiplicities are reported, and defective matrices are flagged as such.

INPUT THAT FITS HOW YOU WORK

• Whole numbers, decimals and fractions such as 3/4
• Paste whole rows at once
• Results as exact fractions or rounded decimals, at a tap
• Arrow keys move between cells
• Share any result to Notes, Mail or Messages

NO ACCOUNT, NO NETWORK, NO TRACKING

Matrix Analysis does not connect to the internet. There is no sign-in, no analytics and no data collection of any kind. Everything you type stays on your device, and every calculation runs on it. It works in airplane mode because it has never needed anything else.

Built for students and engineers who need the answer to be right.
