Matrix
Read full descriptionHide full description
The MatrixAnalysis is carefully designed to be a simple and elegant app. This app has tools to help you analyze matrices like finding eigenvalues and eigenvectors, diagonalization, QR, SLU, LU factorization. This app can also be used to do matrix operations like, finding inverse, determinant, dot product, cross product, and much more. You can also do elementwise operations and scalar operations. Want to do fast fourier transform (FFT) or inverse fourier transform (IFFT), this app is capable of IFFT Want to find an pseudo inverse of a non-square matrix, this app has you covered Want to know a rotation matrix for a given angle or rotate a vector by the given angle? This app has you covered. The expressions and the solutions are displayed in beautiful mathematical way. Once the expressions are solved, a beautifully written solutions are created that you can share with other or save it locally. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. There is also a Study page to help you with learning some important matrix vector formulas and some useful technique. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
Discrete Probability
This app provides a comprehensive tool for learning and calculating discrete probability distributions. It includes formulas with derivations, visual tools like histograms, and descriptions of optimized computation methods. It covers general concepts and several specific distributions.
- User-friendly calculator
- Formulas with derivations
- Exportable formulas (image/LaTeX)
- Optimized computation methods
- Histograms and visual tools
- General concepts and specific distributions

Verdict
The clearest difference is ads: Discrete Probability at none against Matrix's shown. Discrete Probability also leads on update cadence (every 4 days vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
