In an equation, it is placed between two expressions that have the same value, or for which one studies the conditions under which they have the same value. The equals sign ( British English) or equal sign ( American English), also known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense. Here we discuss the introduction, how not equal operator work in matlab and examples, respectively.A well-known equality featuring the equal sign It performs on all data types such as integers, floating numbers, complex variables, characters and strings. The operator performs on each element of input irrespective of dimensionality of input data like single element, single dimension or multiple elements and multidimensionality. In this article, we have seen various ways to use not equal operation in Matlab. And in example 4(b), the first input is an array of words which is compared with a single word, so not equal operator will compare all the words from the first input with the word ‘hello’, and it will also give output in the form of an array. The not equal operation will compare each element from a word with a single letter ‘m’, and it will give a result in the form of an array. In example 4(a), first input is the word ‘hellomatlab’, and the second input is ‘m’, which is a single letter. In this example, we will consider input in forms characters and strings. On such type of dataset, not equal operator compares real and imaginary parts of every element and gives results accordingly, illustrated in example 3. Here the input is multidimensional as well as each element is a complex variable. Previously we have seen simple integers now we will consider a complex variable as elements. In this example type of input, arguments are different. In example 2(b), we can see data is multi-dimensional (matrix) it has three rows and four columns, so not the equal operation will work on every element of the matrix, and it will give result in the form of three rows and four columns. In the previous example, input data was in a single element(single dimension), but if the data has multiple elements then not equal to operation will compare every element from the database and gives output individually for each element, which is illustrated in example 2(a) by using both the methods. In example 1(b) and 1(d), elements are the same therefore, we will get the result as 0 by using both symbolic and syntax methods, respectively. In this two examples, elements are different therefore, we will get the result as 1. In example 1(a), not equal operator used by the symbolic method and in example 1(c), the same problem illustrated by using syntax ‘ne’. ![]() The first element ‘11’ is declared as ‘var 1’, and the second elements ‘29’ is declared as ‘var 2’. ![]() Let us consider one simple example of one element. Given below are the examples of Matlab not equal: Example #1 ![]()
