In this article, we will learn how to write a swift program to display lower triangular matrix. Lower triangular matrix is a matrix in which all the elements above primary diagonal are zero. As shown in the below image: $$\mathrm{\begin{bmatrix} 1 & 0 & 0 & 0 & 0 & ... Read More

In this article, we will learn how to write a swift program to calculate averages using an array. Average is defined as the ratio of the sum of the elements present in the given sequence to the total number of elements available in the given sequence. The general formula of ... Read More

In this article, we will learn how to write a swift program to find the transpose of a matrix. Transpose of a matrix is calculated by interchange the rows of a matrix into columns or columns of a matrix into rows. For example, we have the following matrix: $$\mathrm{X\:=\:\begin{bmatrix} 13, ... Read More

In this article, we will learn how to write a swift program to sort the elements of an array in descending order. To sort the elements of an array Swift provides an in-built function named sort(by:). This function takes one argument and then sorts the array according to the condition ... Read More
