[MxN] now speaks Chinese (Traditional & Simplified) Enhancements and stability improvements were made.

August 14, 2021

This update escalates [MxN]’s capabilities in order to better provide analytical & computational power. Most of the new features were designed around user’s feedback and comments: - You can now save Matrices, Vectors & Constants in memory. - Also delete Matrices, Vectors & Constants from memory. - See a visual representation of the all saved content. - Introducing Script Programming. - Write & evaluate lines of complex expressions. - Centralized matrix laboratory to design, program & run. - Matrix Arithmetic screen has a more cohesive design. - Use a matrix picker to perform all operations. - Help buttons were added to help harness all of [MxN]’s computational power. - [MxN] now habla español (Latin American). - Extract portions of matrices, Expanded Symbology, optimized algorithms & more. Stability updates and enhancements have been made across the board.

August 25, 2020

Update 1.0.6 - App optimization (All algorithms now perform in the background). - Fixed a bug in which the Adjoint option would be available for singular matrices. - Updated social media assets on the tutorial screen.

This version introduces [MxN] social channels to the tens of thousands of mathematicians and scientists using Matrix Numerics around the world! Follow us on Instagram (matrixnumerics), Facebook (Mxn Numerics) & TikTok (matrix.numerics) for tutorials, How-To?’s, Problem Solving, Updates on the platform & much more!! This version includes the following changes and fixes: - Implemented DarkMode across the app. - Fixed an issue in which Projection Vectors would display NaNs. Changed to zeros instead for computations sake. - Fixed an issue in which Angle Between Vectors would display NaNs. Changed to zeros instead for computations sake. - Fixed an issue in which Normalized Vectors would display NaNs. Changed to zeros instead for computations sake. - Fixed an issue in which Orthonormal Vectors would display NaNs. Changed to zeros instead for computations sake. - Fixed issues with the size of the windows presenting Fundamental Subspaces, PLU Decomposition and SVD. - Fixed a crash that would occur when trying to access the algorithms screen for some declared matrices and placeholder. - Fixed padding on the UI for both Vectors and Systems cells. - Added Nullity option for all matrices.

- Updated Tutorial Screen transitions. - Added rational/decimal mode support for real Eigenvalues. - Fixed layouts in the Eigenvalues window. - Fixed layouts in the Eigenvectors window. - Fixed a bug that would crash the app when looking up Fundamental Subspaces of the zero matrix.   - Fixed a big where the Upper Hessenberg decomposition for the zero matrix would give NaNs as outputs and thus crashing by the app when switching to fraction mode. - Fixed labeling issues when declaring column vectors. - Added in-App rating mechanism. - Starting to roll out haptic feedback throughout the App for better expressiveness.

December 11, 2019

- Updated Tutorial Screen layouts for iPads. - Updated Tutorial to reflect latest updates. - Fixed a bug that caused the App to crash when it was first open on some devices. - Fixed an issue where some decompositions for large dimension matrices in fraction mode wouldn’t display full matrices. - Fixed a bug that allowed the Cube matrix input to declare matrices with unsupported dimensions. - Fixed a bug that would render improper latex labels for some matrix operation products. - Added Orthonormalization option for vectors.
