vectogebra 0.0.7

Package that helps you work with vector algebra !

vectogebra v 0.0.7 - 15 May 2022

Python module for vector algebra

easy to use vector algebra library for python, that lets ypu work with vectors in an efficient way. apart from core vector object, many other vector operations are supported. these can be imported from vectogebra.utilities.

this library was made by keeping its applications in Physics in mind (Mechanics, Optics, etc.)

• does not depend on any external libraries except math library.
• fully functional
• easy to use
• supports nearly all vector operations
• beginner friendly
• physics friendly
• Open for modifications

💥 Install

pip install --upgrade vectogebra

⭐ Start by importing the vector class

import vectogebra.vector as vect

OR

from vectogebra import vector as vect

⭐ Also import useful utility functions

import vectogebra.utitlies as vut

OR

from vectogebra import utilities as vut

🔥 Description of the module

this module currently have two components : one is vectogebra.vector, which is the vector class (boject) defination. it contains the basic functionality. the second component, vectogebra.utilities contains useful functions that are defined for the above mentioned vector class like, function to find angle between two vectors, etc.

Create a vector object :

import vectogebra.vector as vect

v1 = vect(1,2,3)

🔢 Algebric operations :

1. Addition

consider two(or more) vectors : a,b,... their sum will be given by : s = a + b + ... sum s will also be a vector object.

2. Subtraction

Vectors can be subtracted using the minus (-) operator.

example :

s = a - b + c - d + ...

resultant s will also be a vector object.

3. Dot product / scalar product and scalar multiplication

the * operator will be used for dot product, or multiplication by a scalar.

example :

p = a * b * c * d * ... is same as "a dot b dot c dot ...".

p = 5*v OR v*5 is same as "scalar 5 multiplied to vector v".

4. Cross product / vector multiplication

the ^ operator will be used for cross product, or vector product.

example :

p = a^b is same as "p equals a cross b".

5. division by a scalar

simply divide a vector by a scalar. NOTE : division by zero or division vector is not supported.

example :

p = v / 5 is same as "p equals v divided by 5".

❌✔️ Logical operations :

1. Equality

a == b returnes True when a and b are equal in magnitude and direction. else, it returns False

2. Inequality

a != b have its usual meaning

3. grater / lesser

the magnitude of the vectors can be compared using common logical operators.

# a and b are vectors
a > b
a < b
a >= b
a <= b

Attributes of the vector object

Components

for a vector v1,

1. v1.x OR v1.i
2. v1.y OR v1.j
3. v1.z OR v1.k

Magnitude

4. v1.magnitude OR vi.mod

Magnitude squared (useful when precesion is required)

5. v1.magnitude_squared OR v1.mod_squared

Type

6. v1.type different from type(v1)
