Description
Matrix Numerics is a powerful Numerical Linear Algebra app with a simple and user-friendly interface. It is designed to quickly present you Linear Algebra results involving matrices and vectors with the fewest taps possible. Matrix Numerics uses the SwiftLAN engine to approximate solutions to a linear system of equations, compute matrix decompositions and calculate vector dynamics. SwiftLAN is a powerful Linear Algebra framework developed by academics for the purpose of native Scientific Computation and Modeling in Swift. Its State-of-the-art Numerical algorithms take advantage of the expressiveness and lightning speed of the Swift programming language to deliver powerful performance and accuracy. Each algorithm in the framework is extensively researched, developed and debugged following closely the mathematical literature of authors like G. Golub, D.S Watkins, J.G.F Francis, C. Van Loan and many others. After development, all algorithms are written 100% in Swift and are intensively tested for speed and accuracy against MATLAB, Accelerate and the LAPACK++ library in C++. All of these aspects make Matrix Numerics a world class tool for scientists, students or any other person exposed to Linear Algebra no matter how early are they in their scientific/mathematical carries. These are some of the things you can do on Matrix Numerics:
* Add, subtract, multiply matrices.
* Inverse
* Condition Number
* Rank
* Spectral Radius
* Trace
* Determinant
* Transpose
* Adjoint
* Characteristic Polynomial
* Eigenvalues & Eigenvectors
* Singular Values
* Singular Value Decomposition
* Pseudoinverse
* PLU Decomposition
* Cholesky Decomposition
* Gram-Schmidt Decomposition
* QR Decomposition
* Upper Hessenberg Decomposition
* Real Schur Form Decomposition
* Norms 1,2,Infinity and Frobenius.
* Fundamental Subspaces
When dealing with Vectors, Matrix Numerics can help you compute:
* Inner Product
* Cross Product
* Projection Vector
* Correlation between vectors
* Angle between vectors
* Vector Length
* Vector Normalization
* Vector Orthonormalization
You can also approximate solutions to Linear System of Equations and Linear Least Squares using the algorithm that best fits your system:
* Ordinary Least Squares
* Iteratively Reweighted Least Squares
* Pseudoinverse by SVD
* Kaczmarz’s Algorithm
* PLU with Scaled Row Pivoting
* Successive Over Relaxation
* Conjugate Gradient
* Gauss-Seidel Iteration
* Jacobi Iteration
Identify specific attributes of your System/Matrix with a single touch:
* Is it Singular?
* Is it Symmetric?
* Is it Positive Definitive?
* Is it Diagonal?
* Is it Upper or Lower Diagonal or both?
* Is it Orthogonal?
* Is it Convergent?
* Is it Row or Column Diagonally Dominant or both?
Numerical results and notations are beautifully rendered in a LaTeX-like style supporting both decimal and rational modes. All matrix computations are preformed in-device on the powerful A-Series Apple chips which means you can use Matrix Numerics everywhere and anywhere with no internet connection required!! Matrix Numerics works on iPhone 6 or newer and all iPads except mini.

Ratings and Reviews
Powerful but needs more specifications
The app is great in its functionality but it is lack of specifications for the buttons on the home page. Users need to guess meanings of buttons. And the app will crash in the script mode if you try to delete the line twice. I think this app will be the best matrix calculator if the developer could add specifications and fix the bug.
Terrible interface
It looks like a promising app with lots of functionality, but the basics of entering data are ignored. Unusable. I couldn't even work out how to add 2 matrices together with the interface. Faster with pen and paper. A wasted opportunity. Please don't waste your time. A text book would be more useful. I get the feeling this was written for his own use and it works well for him. It would have been useful to think about other users though, especially if you're asking people to pay for an app
