gabry

This is a basic implementation of matrix and vectors library to make it understandable in the context of computational matrices

The needed understanding of the library is like this:

1. Gabry is the required library the one that should be used to use others (so it is the imported one)

2. khap6 3shwaa is a randomness library from scratch (still needs a lot of work)

3. sho3a3 is a vector implementation to use as a basis for another library

4. masfofah is a library for matrix operations

Using gabry library (examples)

1. to download the gabry library just clone this repository (Inshaa Allah in the future I will make a pip install of this)

git clone https://github.com/serrysibaee/gabry.git 

Then you can use the gabry library by importing it in the code

from gabry import * 

Then now let's make some matrix to do basic operations on it (Small note: I named the functions using Arabizi typing and I regret it now but too lazy to change it so sorry -smily face- )

making and printing masfofah (matrix)

from gabry import * 

list1 = [[1,2,3,4,5],
         [1,2,3,4,5],
         [1,2,3,4,5]]

#  يصنع مصفوفة
masf = i9n3_masfofatan(list1)

print(masf,masf.shape)

Basic operations

Here we can do add, sub and dot product operation for two matrices (note that in this implementation I did not add the row wise multiply maybe in the future)

from gabry import * 

list1 = [[1,2,3,4,5],
         [1,2,3,4,5],
         [1,2,3,4,5]]
list2 = [[1,2,3,4,5],
         [1,2,3,4,5],
         [1,2,3,4,5]]

# # يصنع مصفوفة
masf1 = i9n3_masfofatan(list1)
masf2 = i9n3_masfofatan(list2)


print(masf1 + masf2)
print(masf1 - masf2)
print(masf1 * masf2.man8ool()) # this is dot product 

some basic functions:

NOTE: that sum() is similar to numpy way to do the axis summation on

from gabry import * 

list1 = [[1,2,3,4,5],
         [1,2,3,4,5],
         [1,2,3,4,5]]

masf1 = i9n3_masfofatan(list1)


# print the shape 
print(masf1.shape)

# transpose
print(masf1.man8ool())

# summation (0 is for rows and 1 is for columns) but it will always return them as a vector
print(masf1.sum(axis=0))
print(masf1.sum(axis=1))

some basic of random functions:

the library khap6_3shwaa is a random number generator that has been added to gabry

rand_mat_int = random_matrix_int(3,3)
print(rand_mat)
rand_mat = random_matrix(3,3)
print(rand_mat)

some things to add in the future inshaa Allah

1. inverse function
2. element wise product (done see in gabry elementwise_product() function)
3. Building pip library for gabry (It's more fancy way but you can use the library by just clone the repository)
4. vectors cross product and norm (NOTE: you can do them by your self as a practice for reminding you see this link link)
5. complete the random library khap6_3shwaa (for refrence see the book numerical recipes chapter 7 (page 340)) {DONE}
