Vectors of Structures:
In numerous applications, involving database applications, information generally would be stored in the vector of structures, instead of in individual structure variables. For illustration, if the Computer Super Mart is storing information on all the software packages which it sells, it would likely be in a vector of structures, the illustration is as shown below,
In this illustration, the packages are vector which has three elements. It is shown as a column vector. Each and every element is a structure consisting of four fields, item_no, price, cost, and code. It may look like a matrix with rows and columns, but it is rather a vector of structures.

Sort algorithm for Sorting vectors of structures: Note that only the price field is compared in the sort algorithm, but the whole structure is replaced. That is therefore each
Function iscellstr - string function: The function iscellstr will return the logical true when a cell array is a cell array of all the strings, or logical false if not. >>
Matrix operations: There are some common operations on matrices. The operators which are applied term by term, implying that the matrices should be of similar size, sometimes
