## Interpolation of a 3D Volume With Numpy and Scipy

Interpolation is a bit complex topic to understand. But to put it in simple words, interpolation refers to the process of finding new points between the given points by using the known data points or values as reference. Interpolation is a technique with which you can estimate unknown data points between two known data points. …

## Converting String to Numpy Datetime64 in a Dataframe

Python contains many open-sourced packages to work on datasets. It also supports a diverse range of data types. When it comes to working on data related to date or time, it is preferred to use the datetime data type instead of the string or float data type, as it helps to keep the data uniform. …

## Numpy linalg.svd: Singular Value Decomposition in Python

In mathematics, a singular value decomposition (SVD) of a matrix refers to the factorization of a matrix into three separate matrices. It is a more generalized version of an eigenvalue decomposition of matrices. It is further related to the polar decompositions. In Python, it is easy to calculate the singular decomposition of a complex or …

## Numpy’s linalg.tensorsolve: Solving Tensor Equations in Python

Python’s powerful and versatile library, Numpy, makes even the most complex mathematical tasks a breeze. Enter Numpy’s linalg.tensorsolve() function and watch it effortlessly solve your tensor linear equations, no matter the dimensions. Tensors, the multi-dimensional arrays that extend beyond vectors and matrices, are easy to work with, thanks to Numpy and its linalg library. Packed …

## Convert A Tensor To Numpy Array In Tensorflow-Implementation

Tensors in python are multi dimensional arrays similar to numpy arrays. They are used as Data containers or data storage units in python. Tensors have a uniform data type. Tensors are also immutable in nature, that is, once the values are assigned they cannot be re-done. In this aspect, tensors are similar to python strings …

## How to Convert Images to Numpy Arrays in Python

In order to train machine learning models on the various dimensions of an image, we need to convert it into a numpy array. Implicitly this is always done, but there are ways to do the same explicitly as well. It can be used for carrying out complex calculations with the speed of light. Libraries such …

## Numpy einsum()- Einstein Summations

Einstein summation is used to simplify tensors, matrices, and vector expressions. It is a notational convention. In python, numpy provides a function named, einsum() that can compute the Einstein summation either implicitly or explicitly, as specified. Numpy in the implicit mode, the einsum() function reduces multi-dimensional arrays in a simple way. When used explicitly, we …

## How To Find Nearest Value In Numpy Array?

Hello readers! There are numerous libraries available to do different functions in Python. The Numpy library is one of them and is used for working with arrays in Python. In many examples like sorting you need to find out the nearest value in an array. In this manner, you can sort the array using this …

## How to normalize a NumPy array to a unit vector?

Numpy or numerical python is a free software tool that makes scientific computations easy in python. It is very powerful python library that provides a huge range of functions for operating on arrays. It contains logical, linear algebraic and also mathematical functions for array manipulation. A numpy array is a matrix like object containing the …

## Numpy LinAlgError – Handling Matrix-related Errors

In python, the Base exception is the class from which all instances of exceptions are derived. Exceptions may be raised by built-in functions or the interpreter or both. User-defined programs can also raise exceptions . One such example of a built-in exception is the LinAlgError. The LinAlgError is raised by the linalg or the linear …
