[MxN] now speaks Chinese (Traditional & Simplified)
Enhancements and stability improvements were made.
1.1
2021-08-14
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.
1.0.6
2020-08-25
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.
1.0.5
2020-07-20
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.
