Data structures:

The Data structures are variables which store more than one value. In order to made sense to store more than one value in a variable, the values must in some way be logically associated. There are several different types of data structures. We have working with one type, arrays example, vectors & the matrices. The array is a data structure in which all the values are logically associated in that they are of similar type, and present in some sense the similar thing. Faraway it is true for the vectors and matrices which we used.

The cell array is a type of data structure which stores values of various types. The Cell arrays can be vectors or matrices; the various values are stored in the elements of the array. The one very general use of a cell array is to store strings of various lengths.

The Structures are data structures which group together values that are logically related, but are not similar thing and not necessarily of the same type. The various values are stored in separate fields of the structure.

The one use of structures is to set up a database of information. For illustration, for a class a professor may want to store information for every student in the class: the student's name, ID number, grades on all the assignments & quizzes, and so forth. In most programming languages and database programs, the terminology is that in a database file, there would be only one record of information for each and every student; each separate piece of information (that is, name, quiz 1 score, etc.) would be called a field of the record. In MATLAB software, such records are termed as structs.
