Calculator for Matrix 4+‎

This is a calculator for linear algebra, a subject taught in university or high school mathematics.
It can be used as a calculator for calculating difficult high-order matrices.

Supported Features
・Scalar of multiples of up to 10 × 10 matrix
・Addition of up to 10 × 10 matrices
・Subtraction of up to 10 × 10 matrices
・Multiplication to a matrix of 10 × 10
・Rank up to 10 × 10 matrix
・Change order of up to 10 × 10 matrices
・Trace up to 10 × 10 matrix
・Power up to 10 × 10 matrices
・Determinant up to 10 × 10 matrix
・Inversion of up to 7x7 matrix
・Adjugate the matrix into a 7x7 matrix
・Transposition of the adjugate matrix to a 7x7 matrix (a matrix with cofactors that correspond to the components of the matrix)
・The eigenvalues ​​of up to 6x6 matrix
・The characteristic equation ​​of up to 6x6 matrix

How to use this application
1. First, enter the matrix values ​​A and B on the input screen. Matrix A and B can be replaced by buttons on the screen.
2. Next, tap the calculation tab at the bottom of the screen, enter the equation on the calculation screen, and press "=" to get the result.
3. If you want to know the determinant, etc. From the matrix you entered, hit the details tab at the bottom of the screen and click the update button to display the output.

Supplements and Notes
・It can also be used as a calculator for real number calculations.
・You can also enter an 8x4 matrix in addition to a square matrix.
・You cannot enter negative numbers in exponents.
・Use a fraction because you cannot enter a decimal point (for example 0.37 = 37/100)
・Please note that if the calculation result is very large, for example 2 ^ 100, the calculation result will be rounded off.
・The functions on the Calculation tab, eigenvalues, and characteristic equation are currently only displayed as decimals.
・When displaying calculation results as decimals, the calculation accuracy will be lower than when displaying them as fractions.
・If an irrational number is entered, the calculation result will be displayed only as a decimal number.
・Fractions can be displayed up to approximately 17 digits in either the denominator or the numerator. If the number of digits exceeds about 17, the display will automatically change to a decimal number.

Features will be added as needed.
