When we move from our academics into the industry, especially engineering individuals, we face a very common problem that we are mainly taught about the obsolete or near obsolete technologies. For example, many schools still use MATLAB. In the engineering sector, whether it is chemical engineer, electrical engineer, or nanoengineer, everyone must have used MATLAB. But in recent times, we can see businesses are shifting from MATLAB to Python. This can be due to a variety of reasons − $1000 licensing cost Inefficient memory allocation Dearth of open source libraries Detest MATLAB syntax. The people who want ... Read More

Dask is a flexible open-source Python library which is used for parallel computing. In this article, we will learn about parallel computing and why we should choose Dask for this purpose. We will compare it with various other libraries like spark, ray and modin. We have also discussed use cases of Dask. Parallel Computing A type of computation known as parallel computing carries out several computations or processes simultaneously. Large issues are typically divided into manageable pieces that may be solved separately. The four categories of parallel computing are Bit-level Instruction-level Data-level Job parallelism. ...

Cleansing, transforming, and analyzing raw data is the first step in the process of obtaining useful, pertinent information which can help businesses make informed conclusions. By offering relevant information and facts, which are usually presented as charts, pictures, tables, and graphs, the strategy helps to lower the risks associated with decision-making. Data analysis is concerned with the process of converting unprocessed data into pertinent statistics, knowledge, and explanations. Data analysis is a crucial competence that may support better decision-making. Spreadsheets are the most often used tools for data analysis, and built-in pivot tables are the most popular analytical tool. ... Read More

Pandas is a Python library that is designed for data manipulation and analysis. It provides the two data structures: Series: It is a one-dimensional labelled array (like a column in a spreadsheet). DataFrame: It is a two-dimensional labelled data structure (like a table), allowing storage of multiple columns with different data types. Using Pandas, we can perform complex data manipulations with the help of its powerful data structures. It can work with different file formats like CSV, Excel, etc. In this article, we will learn how to analyze data activity using ... Read More

In this article, we will learn how to write a swift program to subtract two matrices using multi-dimensional arrays. A matrix is a mathematical structure in which the elements are placed in rows and columns format. For example, the first element is present at a00 location, the second at a01, and so on. So to subtract two matrices we are going to use the - operator to subtract the elements of two matrices like a00 - b00 and then store the sum into a new matrix. For example − Matrix 1 − $\mathrm{\begin{bmatrix}1 & 8 & 4 ewline8 & 8 ... Read More

In this article, we will learn how to write a swift program to search an element in an Array. Here we use the following methods to search elements from the given array: To search Using == operator Using contains() method Using the in function Method 1: Using == operator To search for an element from the given array we iterate through each element of the given array and check if the element is equal to the specified element using the == operator. If true, then the specified element is present in the array. Otherwise not. Algorithm ... Read More

In this article, we will learn how to write a swift program to remove duplicate elements from an array. As we know that an array can store multiple elements of the same type. It is not necessary that all the elements are unique they can be duplicated. For example, arr = [3, 5, 6, 3, 7, 8, 3, 7, 7] here 3 and 7 are duplicate elements. So here we use the following methods to remove duplicate elements − Using contains() method Using Set() initializer Method 1: Using contains() method To remove duplicate elements from the array we ...

In this article, we will learn how to write a swift program to print the absolute value of complex numbers. Complex numbers are those numbers which express in the form of x+yi, where x and y are real numbers and ‘i’ is an imaginary number known as iota. For example 4+2i, 6-4i, etc. Now the absolute value of the complex number is the positive square root of the sum of the squares of the real and the imaginary parts. $\mathrm{|\:Absolute\:Value\:|\:=\:\sqrt{(real)^{2}\:+\:(img)^{2}}}$ For example − Complex number = 4 + 2i $\mathrm{|\:Absolute\:Value\:|\:=\:\sqrt{(4)^{2}\:+\:(2)^{2}}}$ $\mathrm{=\:\sqrt{16 + 4}}$ $\mathrm{=\:\sqrt{20}}$ = 4.4721359549995 Algorithm Step 1 − ...

In this article, we will learn how to write a swift program to print a matrix in Z form. Here we traverse through the first row then the secondary diagonal and then the last row of the matrix to print the z form. For example, 4x4 Matrix − $\mathrm{\begin{bmatrix}4 & 1 & 4 & 1 ewline1 & 3 & 1 & 3ewline2 & 1 & 1 & 2ewline1 & 6 & 6 & 1\end{bmatrix}}$ So the Z form numbers are − $\mathrm{\begin{bmatrix}4 & 1 & 4 & 1 ewline & & 1 & ewline & 1 & & ...

In this article, we will learn how to write a swift program to print an identity matrix. Identity matrix is a square matrix in which the main diagonal elements contain only one and the rest of the elements are 0. For example − $\mathrm{Matrix\:=\:\begin{bmatrix}1 & 0 & 0 & 0 & 0 ewline0 & 1 & 0 & 0 & 0 ewline0 & 0 & 1 & 0 & 0ewline0 & 0 & 0 & 1 & 0ewline0 & 0 & 0 & 0 & 1\end{bmatrix}}$ Algorithm Step 1 − Create a function. Step 2 − In this function, use ... Read More
