string cell array matlab different lengths

It returns a new structure with the field removed, but does not modify the original structure (unless the returned structure is assigned to that variable). fprintf: Can only display a single value of the structure at a time >disp(package) >fprintf('this is a number %d',em_no) rmfield: Removes a field from a structure. The first input will create the structure 'package' Displaying structures: 1. dot operator > em_no = 123 > st = 19.99 > package.price = 39.95 > de = 'g' The variable 'package' does not need to be preallocated. They do not have elements that are indexed, so it is not possible to loop through the values in a structure. However, structure variables are not arrays. Advantage of structures is that the fields are named, which helps to make it clear what values are stored in the structure. Structures: Data structures that group values together that are logically related in fields of the structure. Structures, on the other hand, are not indexed the values are referenced using the names of the fields, which can be more mnemonic than indexing. Differences: -Cell arrays are indexed, and can therefore be used with loops or vectorized code. Each student would be a single record, but in matlab the records are called 'structs' Similarities: Both cell arrays and structures can be used to store values that are different types in a single variable.

The different values are stored in separate fields of the structure -Use: One use of structures is to set up a database of information (ex: student name, ID, test scores, attendance). Structures: A form of data structures that group together values that are logically related, but are not the same thing and not necessarily the same type. Cell arrays actually store pointers to the stored data. Use: Store strings of different lengths. Cell arrays can be VECTORS OR MATRICES the different values are referred to as the elements of the array. Cell Array: A kind of data structure that stores values of different types. There are many different kinds of data structures. For it to make sense to store more than one value in a variable, the values should somehow be logically related. You can throw anything you want into the bucket: a string, an integer, a double, an array, a structure, even another cell array. Data structure: Variables that store more than one value.
