+# [latex2sympy2](https://github.com/OrangeX4/latex2sympy)
+
+## About
+
+`latex2sympy2` parses **LaTeX math expressions** and converts it into the equivalent **SymPy form**. The latex2sympy2 is adapted from [augustt198/latex2sympy](https://github.com/augustt198/latex2sympy) and [purdue-tlt / latex2sympy](https://github.com/purdue-tlt/latex2sympy).
+
+This project is a part of a VS Code extension called [Latex Sympy Calculator](https://marketplace.visualstudio.com/items?itemName=OrangeX4.latex-sympy-calculator). It is designed for providing people writing in latex or markdown a ability to calculate something when writing math expression.
+
+[ANTLR](http://www.antlr.org/) is used to generate the parser.
+
+## Features
+
+* **Arithmetic:** Add (+), Sub (-), Dot Mul (·), Cross Mul (×), Frac (/), Power (^), Abs (|x|), Sqrt (√), etc...
+* **Alphabet:** a - z, A - Z, α - ω, Subscript (x_1), Accent Bar(ā), etc...
+* **Common Functions:** gcd, lcm, floor, ceil, max, min, log, ln, exp, sin, cos, tan, csc, sec, cot, arcsin, sinh, arsinh, etc...
+* **Funcion Symbol:** f(x), f(x-1,), g(x,y), etc...
+* **Calculous:** Limit ($lim_{n\to\infty}$), Derivation ($\frac{d}{dx}(x^2+x)$), Integration ($\int xdx$), etc...
+* **Linear Algebra:** Matrix, Determinant, Transpose, Inverse, Elementary Transformation, etc...
+* **Other:** Binomial...
+
+**NOTICE:** It will do some irreversible calculations when converting determinants, transposed matrixes and elementary transformations...
+
+## Installation
+
+```
+pip install latex2sympy2
+```
+
+**Requirements:** `sympy` and `antlr4-python3-runtime` packages.
+
+## Usage
+
+### Basic
+
+In Python:
+
+```python
+from latex2sympy2 import latex2sympy, latex2latex
+
+tex = r"\frac{d}{dx}(x^{2}+x)"
+# Or you can use '\mathrm{d}' to replace 'd'
+latex2sympy(tex)
+# => "Derivative(x**2 + x, x)"
+latex2latex(tex)
+# => "2 x + 1"
+```
+
+### Examples
+
+|LaTeX|Converted SymPy|Calculated Latex|
+|-----|-----|---------------|
+|`x^{3}` $x^{3}$| `x**3`|`x^{3}` $x^{3}$|
+|`\frac{d}{dx} tx` $\frac{d}{dx}tx$|`Derivative(x*t, x)`|`t` $t$|
+|`\sum_{i = 1}^{n} i` $\sum_{i = 1}^{n} i$|`Sum(i, (i, 1, n))`|`\frac{n \left(n + 1\right)}{2}` $\frac{n \left(n + 1\right)}{2}$|
+|`\int_{a}^{b} \frac{dt}{t}`|`Integral(1/t, (t, a, b))`|`-\log{(a)} + \log{(b)}` $-\log{(a)} + \log{(b)}$|
+|`(2x^3 - x + z)|_{x=3}` $(2x^3 - x + z)\|_{x=3}$|`z + 51`| `z + 51` $z + 51$ |
+
+If you want to read the math formula, you can click [GitNotes](https://notes.orangex4.cool/?git=github&github=OrangeX4/latex2sympy).
+
+### Solve Equation
+
+``` latex
+# Before
+x + y = 1
+
+# After
+[ y = 1 - x, \  x = 1 - y]
+```
+
+### Eval At
+
+``` latex
+# Before
+(x+2)|_{x=y+1}
+
+# After
+y + 3
+```
+
+### Matrix
+
+#### Identity matrix
+
+```
+tex = r"\bm{I}_3"
+latex2sympy(tex)
+# => "Matrix([[1, 0, 0], [0, 1, 0], [0, 0, 1]])"
+```
+
+#### Determinant
+
+``` python
+from latex2sympy2 import latex2sympy
+
+tex = r"\begin{vmatrix} x & 0 & 0 \\ 0 & x & 0 \\ 0 & 0 & x \end{vmatrix}"
+latex2sympy(tex)
+# => "x^{3}"
+```
+
+#### Transpose
+
+``` python
+from latex2sympy2 import latex2sympy
+
+tex = r"\begin{pmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{pmatrix}^T"
+# Or you can use "\begin{pmatrix}1&2&3\\4&5&6\\7&8&9\end{pmatrix}'"
+latex2sympy(tex)
+# => "Matrix([[1, 4, 7], [2, 5, 8], [3, 6, 9]])"
+```
+
+#### Elementary Transformation
+
+``` python
+from latex2sympy2 import latex2sympy
+
+matrix = r'''
+    \begin{pmatrix}
+        1 & 2 & 3 \\ 
+        4 & 5 & 6 \\
+        7 & 8 & 9 \\ 
+    \end{pmatrix}
+'''
+
+# Scale the row with grammar "\xrightarrow{kr_n}"
+tex = matrix + r'\xrightarrow{3r_1}'
+latex2sympy(tex)
+# => "Matrix([[3, 6, 9], [4, 5, 6], [7, 8, 9]])"
+
+# Swap the cols with grammar "\xrightarrow{c_1<=>c_2}"
+# Of course, you can use "\leftrightarrow" to replace "<=>" 
+tex = matrix + r'\xrightarrow{c_1<=>c_2}'
+latex2sympy(tex)
+# => "Matrix([[2, 1, 3], [5, 4, 6], [8, 7, 9]])"
+
+# Scale the second row and add it to the first row
+# with grammar "\xrightarrow{r_1+kr_2}"
+tex = matrix + r'\xrightarrow{r_1+kr_2}'
+latex2sympy(tex)
+# => "Matrix([[4*k + 1, 5*k + 2, 6*k + 3], [4, 5, 6], [7, 8, 9]])"
+
+# You can compose the transform with comma ","
+# and grammar "\xrightarrow[4r_3]{2r_1, 3r_2}"
+# Remember the priority of "{}" is higher than "[]"
+tex = matrix + r'\xrightarrow[4r_3]{2r_1, 3r_2}'
+latex2sympy(tex)
+# => "Matrix([[2, 4, 6], [12, 15, 18], [28, 32, 36]])"
+```
+
+### Variances
+
+``` python
+from latex2sympy2 import latex2sympy, variances, var, set_variances
+
+# Assign x a value of 1
+latex2sympy(r"x = 1")
+
+# Assign x a matrix symbol with dimension of n x m
+latex2sympy(r"x \in \mathbb{R}^{n \times m}")
+
+# Calculate x + y
+latex2sympy(r"x + y")
+# => "y + 1"
+
+# Get all variances
+print(variances)
+# => "{x: 1}"
+
+# Get variance of "x"
+print(var["x"])
+# => "1"
+
+# Reset all variances
+set_variances({})
+latex2sympy(r"x + y")
+# => "x + y"
+```
+
+### Complex Number Support
+
+``` python
+from latex2sympy2 import set_real
+
+set_real(False)
+```
