## How to Check If String is Empty or Not in Python

String data type in Python is immutable; that means you can not change a string once defined.  String with spaces is actually an empty string but has non-zero size. So, when you check the empty string with len() or not operator, it counts…

## Python Dictionary of Lists

You can say that Python dictionaries are associative arrays. You can define a dictionary by surrounding a comma-separated list of key-value pairs in curly braces ({ }). The colon(:) separates each key from its associated value. Let's see…

## Numpy linalg tensorsolve() Function in Python with Example

Numpy linalg tensorsolve() function is used to calculate the equation of ax=b for x. It is assumed that all x indices are summarized above the product and the right indices of a, as is done. For example, tensordot (a, x, axes = b.ndim).…

## Numpy linalg slogdet() Function in Python with Example

Numpy linalg slogdet() function is used to compute the sign and (natural) logarithm of an array's determinant. Now the question is when we need this slogdet()? If most lists have too little or too little index, then the call to det() can…

## Numpy linalg solve() Function in Python Example

Numpy linalg solve() function is used to solve a linear matrix equation or a system of linear scalar equation. The solve() function calculates the exact x of the matrix equation ax=b where a and b are given matrices.  Numpy linalg…

## Numpy linalg svd() Function in Python Example

Numpy linalg svd() function is used to calculate Singular Value Decomposition. If a 2D array, it is assigned to u @ np.diag (s) @ vh = (u * s) @ vh, where no vh is a 2D composite arrangement and a 1D range of singular values. When a is…

## Numpy linalg qr() Function in Python Example

Python numpy linalg qr() function is used to calculate the QR factorization of a given matrix. In the term “qr”, q is orthonormal, and r is upper-triangular. Numpy linalg qr() The np qr() function computes the qr factorization of a…

## Numpy linalg cholesky: How to Use np cholesky() in Python

Python numpy.linalg.cholesky() is used to get Cholesky decomposition value. Let’s understand what Cholesky decomposition is. If we have L * L.H, of a square matrix a, where L is the lower triangle and .H is the conjugate transpose operator…

## Numpy kron: How to Use np kron() Function

Numpy kron() method is used to get the Kronecker product of two given lists. But wait, what is the Kronecker product? Suppose we have two lists: A and B . If we want to calculate the Kronecker product of these two lists, the answer will…

## Numpy linalg matrix_power: How to Calculate Power of Matrix

Numpy linalg.matrix_rank() is used to calculate the power n of a square matrix. What does that mean is that if we have a square matrix M and we have an integer n, then this function is used to calculate Mn? Numpy linalg matrix_power()…

## Numpy outer: How to Calculate Product of Vectors in Python

Numpy outer() is used to calculate the outer product of two given vectors. Now the question is what is the outer product? Suppose we have two vectors A and B , the outer product of these two vectors will be:       ]  Numpy.outer()…
