Comparing Two Cell Arrays of Strings
ismember(a,b): It compares the ‘a’ and ‘b’ cell arrays and returns a logical array which has 0 and 1 of size same as of cell array ‘a’. It returns 0 if the element in cell array ‘a’ is not present in cell array ‘b’. If it is present it returns 1.
setdiff(a,b): It compares the ‘a’ and ‘b’ cell arrays and returns an array that has elements from cell array ‘a’ that are not there in cell array ‘b’.
Syntax:
ismember(a,b)
setdiff(a,b)
Example 1 :
Matlab
% MATLAB code A = { 'gfg' , 'geeks' , 'w3wiki' }; B = { 'gfg' , 'iam' , 'show' }; |
Output:
ismember(A,B) , 1×3 logical array = [1, 0, 0] setdiff(A,B) , 1×2 cell array = {'geeks'} {'w3wiki'}
Explanation:
‘gfg’ is present in both the cell arrays hence the first element in the array is 1. The other two are 0 because ‘geeks’ and ‘geeks for geeks’ both are not present in the cell Array B. setdiff is returning cell array {‘geeks’} {‘w3wiki’} because they are the elements from the cell Array A that are not present in cell Array B.
Example 2:
Matlab
% Cell Array A A = { 'gfg' , 'geeks' , 'w3wiki' } %Cell Array B B = { 'gfg' , 'iam' , 'show' } % ismember function ismember(A,B) % setdiff function setdiff(A,B) |
Output:
1 0 0 {'geeks'} {'w3wiki'}
Example 3:
Matlab
% Cell Array A A = { 'program' , 'matlab' } %Cell Array B B = { 'matlab' , 'programming' , 'gfg' } % ismember function ismember(A,B) % setdiff function setdiff(A,B) |
Output:
0 1 {'program'}
Comparing Two Cell Arrays of Strings of Different Sizes in MATLAB
MATLAB is a high-performance language that is used for matrix manipulation, performing technical computations, graph plottings, etc. It stands for Matrix Laboratory.
- Cell Array: A cell Array in MATLAB is a data type that can store any type of data. Data is stored in cells in a cell array. It is initialized using { } i.e. curly braces. E.g. A = { 5, “gfg” , 7.2 }
- Accessing a Cell Array: To access a cell array we use curly braces and its index. Indexing starts with 1. E.g. A = { 5, “gfg” , 7.2 }
Now A{1} will return 5, A{2} will return “gfg” and A{3} will return 7.2
