## What is n Matrix Calculator?

Application Functions
1. Calculation for a single matrix
Find determinant, inverse matrix, eigenvalues, and eigenvectors of any square matrix.

2. Matrix calculation using expression
Input any square matrix to A, B, C, and D, respectively, and calculate values based on mathematical expressions such as (8A-6B)*1C+9D

3. Calculation of simultaneous equations
Calculates simultaneous equations expressed in matrix form as Ax = b, where A is a square matrix and b is a vertical vector.



Features of the application
1. All functions support complex numbers.
Complex matrices, eigenvalues and eigenvectors are supported even when they are complex numbers.

2. Arbitrary square matrices can be calculated.
Supports not only basic matrices such as 2 x 2 and 3 x 3, but also high-dimensional matrices such as 100 x 100.

3. Copy and paste from spreadsheet software
Calculations can be performed by copying and pasting cells from spreadsheets such as Excel and Numbers.
Please be careful of line breaks after pasting.

4. Fast calculation speed
Even for a 100 x 100 matrix, determinant, inverse matrix, rank, eigenvalue, and eigenvector can be calculated in only 1 second.

5. Can be used offline
You can perform matrix calculations anytime, anywhere.



How to use
1. In case of inputting an actual matrix or CSV
Use newlines and commas to represent matrices as follows.

2,6,7
8,11,3.5
65,3,11

Please do not include spaces.


2. In case of executable matrix and Space input
Use line breaks and commas to represent matrices as follows

2 6 7
8 11 3.5
65 3 11

This input method allows you to copy and paste spreadsheet cells
Do not include more than two spaces.


3. For complex matrix and CSV input
Use line breaks and commas to represent matrices as follows

1+2i,-3i
4,0

Please do not include spaces.
Please add coefficients, even if they are i or -i
i → 1i -i → -1i  


4. For complex matrix and Space input
Use line breaks and commas to represent matrices as follows

1+2i -3i
4 0

Do not put more than two spaces.
Please add a coefficient, even if it is i or -i
i → 1i -i → -1i
