# How to find the Rank of a Matrix?

# How to find the Rank of a Matrix?

This recipe helps you find the Rank of a Matrix

This python source code does the following: 1. Creates custom numpy matrix 2. Uses "linalg" and "matrix_rank" function for calculating rank of matrix

In [1]:

```
## How to find the Rank of a Matrix
def Kickstarter_Example_12():
print()
print(format('How to find the Rank of a Matrix','*^72'))
# Load library
import numpy as np
# Create matrix
matrixA = np.array([[1, 2, 3, 23],
[4, 5, 6, 25],
[7, 8, 9, 28],
[10, 11, 12, 41]])
# Return the Rank of a Matrix
print(); print("The Rank of a Matrix: ",
np.linalg.matrix_rank(matrixA))
Kickstarter_Example_12()
```

In this machine learning resume parser example we use the popular Spacy NLP python library for OCR and text classification.

In this NLP AI application, we build the core conversational engine for a chatbot. We use the popular NLTK text classification library to achieve this.

In this machine learning churn project, we implement a churn prediction model in python using ensemble techniques.

Data Science Project - Build a recommendation engine which will predict the products to be purchased by an Instacart consumer again.

In this deep learning project, we will predict customer churn using Artificial Neural Networks and learn how to model an ANN in R with the keras deep learning package.

In this project, we are going to work on Deep Learning using H2O to predict Census income.

In this data science project in R, we are going to talk about subjective segmentation which is a clustering technique to find out product bundles in sales data.

This project analyzes a dataset containing ecommerce product reviews. The goal is to use machine learning models to perform sentiment analysis on product reviews and rank them based on relevance. Reviews play a key role in product recommendation systems.

In this machine learning project, we will use binary leaf images and extracted features, including shape, margin, and texture to accurately identify plant species using different benchmark classification techniques.

The goal of this data science project is to build a predictive model and find out the sales of each product at a given Big Mart store.
