There are other exceptions as well, which should be taken into account before dealing with ismember function in Matlab.I am using a cell array to contain 1×2 vectors of grid locations in the form. 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
