# How to Divide each element of a matrix by a numerical value?

# How to Divide each element of a matrix by a numerical value?

This recipe helps you Divide each element of a matrix by a numerical value

This python source code does the following 1. Creates your won numpy array 2. Uses lambda function to perform arithmetic manipulation 3. Uses vectorize function to perform arithmetic manipulation

In [1]:

```
## How to Divide each electment of a matrix by a numerical value
def Kickstarter_Example_18():
print()
print(format('How to divide each element of a matrix by a numerical value',
'*^72'))
# Load library
import numpy as np
# Create two vectors
matrixA = np.array([[2, 3, 23],
[5, 6, 25],
[8, 9, 28]])
# Create a function that adds 100 to something
add_100 = lambda i: i / 9
# Create a vectorized function
vectorized_add_100 = np.vectorize(add_100)
# Apply function to all elements in matrix
print(); print(vectorized_add_100(matrixA))

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 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.

In this ensemble machine learning project, we will predict what kind of claims an insurance company will get. This is implemented in python using ensemble machine learning algorithms.

In this machine learning pricing project, we implement a retail price optimization algorithm using regression trees. This is one of the first steps to building a dynamic pricing model.

Data Science Project in R -Build a machine learning algorithm to predict the future sale prices of homes.

Text data requires special preparation before you can start using it for any machine learning project.In this ML project, you will learn about applying Machine Learning models to create classifiers and learn how to make sense of textual data.

Machine Learning Project in R- Predict the customer churn of telecom sector and find out the key drivers that lead to churn. Learn how the logistic regression model using R can be used to identify the customer churn in telecom dataset.

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.
