Matrix-Analysis 與 Matrix Solver Step by Step 使用情況與統計
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!

“Matrix Solver Step by Step” Linear Algebra learning tool and a Matrix Calculator:
* Performs most commonly used matrix calculations and decompositions (see list below).
* Demonstrates and explains algorithm steps for almost all the functions.
* Draws interactive geometric references when appropriate.
* Provides tutorials (explanations and proofs) for most Linear Algebra concepts. The tutorial topics have links to all other relevant topics, making them understandable for users with minimal prior knowledge of Linear Algebra.
Every effort is being made to ensure user friendly interface and factual accuracy.
The app is, so far, free of charge and free of ads.
It is being continuously updated with new functions, graphs, and proofs.
Suggestions and corrections are welcome!
Write to us at graphmath@aol.com.
