Added rank of matrix in linear algebra #8687

rudransh61 · 2023-04-24T11:16:16Z

Hi i am rudransh ,
I added a python file to find rank of matrix because i cannot find it anywhere in code base .
So, i thought that "lets contribute ".
Please try to pull this so that the set of algorithm will be completed.
If there is any error , inform me i will try to correct this.
AND AT LAST I WOULD LIKE TO SAY PLEASE SET IT UP IN A VIRTUAL ENVIRONMENT SO THAT NEW VERSIONS OF REQUIREMENT AND PYTHON WILL NOT AFFECT ANYONE..
THANK YOU FOR READING THIS
A PROGRAMMER

To resolve ruff errors, you should rename these functions to use lowercase letters. For example, you could rename "swapRows" to "swap_rows", "Row_Transformation" to "row_transformation", and "MatrixRank" to "matrix_rank".

Ok let me try

rohan472000

The error message you received in pre-commit indicates that the file "Rank_of_Matrix.py" contains uppercase characters in its filename, which violates a common naming convention for Python files.

To resolve this error, you should rename the file to use lowercase letters instead. For example, you could rename it to "rank_of_matrix.py" instead.

rohan472000

Kindly rename as I have suggested

rudransh61 · 2023-04-25T10:16:17Z

I want 1 week because i had found some bugs in file
so after some time it will ready for production

rudransh61 · 2023-04-25T10:38:12Z

i had completed all but failing in changing the file name
i you can then please help me to change the name
before pushing it on repository the name was "rank_of_matrix" but after i pushed it into repository idk why it changed into "Rank_of_Matrix" ???

rudransh61 · 2023-04-25T10:38:33Z

now all the errors and naming patterns are corrected except the name

for more information, see https://pre-commit.ci

rohan472000

it should be rank_of_matrix.py because it is a standard practice to write file name in lowercase.

rudransh61 · 2023-04-26T02:03:41Z

finnally after trying for 2hrs i renamed the file

rudransh61 · 2023-04-26T08:00:55Z

doneee

rudransh61 · 2023-04-26T08:01:43Z

and thank you for your feedbacks

rudransh61 · 2023-04-26T11:06:59Z

....is it ok to merge pull request or it is not okay

rudransh61 · 2023-04-28T04:42:56Z

.....can you merge this fork

rohan472000 · 2023-04-28T05:44:04Z

I'm just a contributor, I don't have write access.
Kindly ask @cclauss for a review.

how can i ask him for review??

Please add: >>> rank_of_matrix([[]])
