Read this article to understand the process of finding the exact string in a cell array in MATLAB. MATLAB is extensively used in different field of science, engineering, finance, economics, and more. MATLAB stands for Matrix Laboratory, it is a programming and interactive platform developed by MathWorks to provide a variety of tools for programming mathematical functions and operations, data analysis, etc. There are other exceptions as well, which should be taken into account before dealing with ismember function in Matlab.MATLAB is a programming environment developed for scientists and engineers to design and analyze system, perform data analysis, create visualizations, and more. If the input array is of type datetime then they should be consistent. If Y is of type table or timetable, then the variable names should be the same as that of X.If the arrays are of type categorical, then the type of categories and their order of values should be the same.If the array is of type categorical, then they can be included with string, character or cell arrays.Character or string arrays can be combined with cell arrays if they are of character vectors.If one of the arrays is of type double then they can be combined with char, logical and numeric classes.The class of the input arrays should be the same with some exceptions: If the rows option is specified in the syntax, then the input arrays should have the same number of columns. The input arrays can be logical, numeric, character, string, datetime, categorical, tables, timetables, duration, etc. If the values are not present in Y, then the location value will be 0. The second element which is present in Y is 3 and the respective position is 5, 2 is present in the 2 nd position in Y. So, the first element of X i.e.4 is present in Y at only position 3, so it will return 3. After that, we have given another variable in syntax to determine the lowest index of the values of X that are present in Y. After checking that, it returns the resultant values in the form of 1 and 0 which can be seen for LX. In the above example, ismember function first checks whether the values present in X are also a part of Y or not. To determine the corresponding location of the values that are present in Y array. 6 is not present in Y, so the resultant value is 0. Similarly, the values at the 3 rd and 4 th positions are also present in the Y, so the resultant values are 1. 4 is present in Y, so the first value of the resultant LX is 1. In the above example, ismember function checks whether the elements present in X are also present in Y and returns the logical values in the form of 1 and 0. To check whether the elements of X are present in Y. Legacy option is not supported if the types of arrays are categorical, datetime, duration, timetables or tables.īelow examples explain the concept of ismember function in Matlab: Example #1 =ismember (_,” legacy option”): If the legacy option is mentioned in the syntax, then the properties and behaviour of ismember function is considered from R2012b versions and previous releases.If the value is 0, then X is not in the row of Y. If X and Y are in the form of tables or timetables, then LocationY contains the lowest index of Y, provided that rows in X should be a part of rows in Y. If there are rows option specified in the syntax, then LocationY contains the lowest index of Y, provided that rows in X should be a part of rows in Y. If the value is 0, then it indicates that the elements present in X are not a part of Y. =ismember (_): Here LocationY is used to find the lowest index values present in Y if the values present in X are a member of Y.The rows option is not valid if cell arrays are used, provided that the input array is categorical or datetime array. If the values are present, then it returns logical 1 (True) else it returns logical 0 (False). Lx=ismember (X, Y, rows): This syntax considers the rows of X and Y as single entities and determines the logical values which are in the form of 1 and 0.The resultant value Lx is a column vector. If X and Y are in the form of tables or timetables, then it returns the logical value for every row present and if X and Y are in the form of timetables, then row times are considered. If the elements are present, then it returns 1(True) else it returns 0(False). Lx=ismember (X, Y): This checks whether the elements in X is present in Y.Please find the below syntaxes which are used in Matlab considering ismember function: The result is in the form of logical 1 (True) or logical 0 (False). In Matlab, we can check if a particular element belongs to an array or not by using ismember () function.
