Anvaya (अन्वय) - A comprehensive Python mathematics library inspired by ancient Indian mathematical traditions

Project description

Anvaya (अन्वय) - Comprehensive Python Mathematics Library

PyPI version License: MIT Python 3.8+ Maintenance

Anvaya (Sanskrit: अन्वय) means "logical connection" or "coherent reasoning." It represents the systematic thread that links mathematical premises to universal truths.

Anvaya is a production-ready, high-performance mathematics library for Python. It bridges the gap between symbolic reasoning and numerical computation, providing a unified interface for 14 different mathematical domains.

�📦 Installation

Anvaya requires Python 3.8 or higher. Use pip to install:

pip install anvaya

🚀 Quick Start

Solving a complex problem with Anvaya is intuitive. Here is a 30-second example of symbolic variables, algebra, and calculus working together:

from anvaya import algebra, calculus
from anvaya.symbolic import var

# 1. Define variables
x = var('x')

# 2. Expand a polynomial
polynomial = (x + 3)**2
expanded = algebra.expand_poly(polynomial)
print(f"Expanded: {expanded}")  # x**2 + 6*x + 9

# 3. Find the derivative
derivative = calculus.diff(expanded, x)
print(f"Derivative: {derivative}")  # 2*x + 6

# 4. Solve for roots
roots = algebra.solve_linear(derivative, x)
print(f"Roots: {roots}")  # [-3]

🧮 Domain Guides

1. Algebra

Handle equations, polynomials, and simplifications with ease.

from anvaya import algebra
from anvaya.symbolic import var

x = var('x')

# Solve quadratic equation x^2 - 5x + 6 = 0
roots = algebra.solve_quadratic(x**2 - 5*x + 6, x)
print(roots)  # [2, 3]

# Factorize expression
expr = x**2 + 2*x + 1
print(algebra.factor_poly(expr))  # (x + 1)**2

2. Linear Algebra

Perform matrix operations with high precision and safe error handling.

from anvaya import linear_algebra as la
import numpy as np

# Create a matrix
A = la.matrix([[1, 2], [3, 4]])

# Calculate Determinant
print(la.determinant(A))  # -2.0

# Compute Eigenvalues and Eigenvectors (Structured Result)
result = la.eigenvalues(A)
print(f"Values: {result.values}")
print(f"Vectors:\n{result.vectors}")

# Solve System Ax = b
b = [5, 11]
x = la.solve_linear_system(A, b)
print(f"Solution: {x}") # [1.0, 2.0]

3. Calculus

Perform symbolic differentiation, integration, and limit calculations.

from anvaya import calculus
from anvaya.symbolic import var

x = var('x')

# Differentiation
print(calculus.diff(x**3, x))  # 3*x**2

# Definite Integration (from 0 to 1)
integral = calculus.integrate(x**2, x, 0, 1)
print(integral)  # 1/3

# Limits
print(calculus.limit(1/x, x, 0, direction='+'))  # oo (Infinity)

4. Probability & Statistics

Modern API for distributions and descriptive statistics.

from anvaya import probability as prob
from anvaya import statistics as stats

# Statistics
data = [10, 20, 20, 30, 40, 50]
print(stats.mean(data))    # 28.33
print(stats.median(data))  # 25.0

# Probability Distributions
normal = prob.Normal(mean=0, std=1)
print(normal.pdf(0))  # 0.3989 (Bell curve peak)
print(normal.cdf(0))  # 0.5 (Area to the left)

# Bayes Theorem
# P(A|B) = P(B|A)*P(A) / P(B)
prob_a_given_b = prob.bayes_theorem(p_b_given_a=0.9, p_a=0.01, p_b=0.05)
print(f"Probability: {prob_a_given_b}") # 0.18

5. Number Theory

Prime numbers, modular arithmetic, and ancient algorithms.

from anvaya import number_theory as nt

# Prime factorization
print(nt.prime_factors(360))  # {2: 3, 3: 2, 5: 1}

# Euler's Totient
print(nt.totient(10))  # 4 (Numbers 1, 3, 7, 9 are coprime to 10)

# Modular Inverse
print(nt.mod_inverse(3, 11))  # 4 (3*4 = 12 ≡ 1 mod 11)

# Greatest Common Divisor
print(nt.gcd(48, 18))  # 6

6. Numerical Methods

Root finding and numerical integration when symbolic math isn't enough.

from anvaya import numerical

# Find root of f(x) = x^2 - 2 near x=1.5
def f(x): return x**2 - 2
root = numerical.root_find(f, 1.5)
print(f"Square root of 2 is approx: {root:.6f}") # 1.414214

🛠 Advanced Features

Safe Error Handling

Anvaya doesn't just crash; it tells you why a calculation failed using custom exceptions.

from anvaya import linear_algebra as la
from anvaya import SingularMatrixError

A = [[1, 1], [1, 1]] # Singular matrix (no inverse)

try:
    inv = la.inverse(A)
except SingularMatrixError as e:
    print(f"Math Error: {e}") # Matrix is singular or nearly singular

Type Safety

Full support for Python type hints and PEP 561 compliance, making it perfect for large-scale applications with VS Code or PyCharm.


🧬 Symbolic Engine

The core of Anvaya is its SymbolicEngine. You can use it to parse strings into math or manipulate variables.

from anvaya.symbolic import engine

# Parse from string
my_math = engine.expr("x**2 + 2*x + 1")
print(engine.factor(my_math)) # (x + 1)**2
