Swift Program to Compute the Sum of Diagonals of a Matrix
In this article, we will learn how to write a swift program to compute the sum of diagonals of a matrix. Every matrix has two diagonals which are known as primary and secondary diagonals. For example, we have the following 5x5 square matrix − 2 3 4 5 6 4 6 7 8 9 1 1 1 3 4 4 0 4 0 4 0 0 1 1 1 So the primary diagonal is formed by using elements 2, 6, 1, 0, 1 and the secondary diagonal is formed by using elements 6, 8, 1, 0, 0. Hence the ...

In this article, we will learn how to write a swift program to display upper triangular matrix. Upper triangular matrix is a matrix in which all the elements below the primary diagonal are zero. As shown in the below image − $$\mathrm{\begin{bmatrix} 1 & 4 & 6 & 7 & 8 & 8ewline 0 & 5 & 6 & 8 & 9 & 9ewline 0 & 0 & 6 & 7 & 8 & 3ewline 0 & 0 & 0 & 2 & 1 & 1ewline 0 & 0 & 0 & 0 & 2 & 1ewline 0 & 0 ...
Read MoreSwift Program to Find the Sum of the Boundary Elements of a Matrix
In this article, we will learn how to write a swift program to find the sum of the boundary elements of a matrix. Boundary elements of a matrix are those elements that are present on the boundary of the matrix that are elements in the first row, last row, first column, and last column. For example − Given Matrix: 2 4 5 6 7 8 4 5 6 7 3 2 3 4 5 6 2 1 1 1 1 1 1 1 3 4 3 4 3 4 2 2 2 2 2 2 Boundary elements are: ...
Read MoreSwift Program to Find the Trace and Normal of a given Matrix
In this article, we will learn how to write a swift program to find trace and normal of a given matrix. Calculating the Trace of a given Matrix Trace is known as the sum of primary diagonal elements of the given square matrix. For example, we have a 3x3 square matrix − 2 3 4 3 4 6 1 3 2 So the primary diagonal elements are 2, 4 and 2. Hence the trace of the given 3x3 matrix is 2+4+2 = 8. Algorithm Step 1 − Define the size of the matrix. Step 2 − Create a ...

In this article, we will learn how to write a swift program to interchange the elements of first and last in a matrix across rows. Therefore, to interchange the elements we need to swap the elements of the first row with the elements of the last row of the given matrix. For example − Original matrix: 2 4 5 6 3 4 6 2 6 7 7 2 1 1 1 1 So after swapping the first and last rows we get: 1 1 1 1 3 4 6 2 6 7 7 2 2 4 5 6 ...

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 average is − Average = (p1+p2+p3+..+pn)/n Here we use the following methods to calculate the average using array − Using pre−define functions Without using predefine functions Method 1: Using Pre-Define Functions To find the average of the given array, we use reduce() method to find the sum ...
