Sorting Vectors of structures:
Whenever working with vector of structures, it is very common to sort based on a particular field within the structures. For illustration, recall the vector of structures used to the store information on various software packages.
Here is a function which sorts this vector of structures in ascending order depend on the price field.
Note that only the price field is compared in the sort algorithm, but the whole structure is replaced. That is therefore each element in the vector, that is a structure of information about a specific software package, that remains intact.
Anonymous Functions: The anonymous function is a very easy, one-line function. The benefit of an anonymous function is that it does not have to be stored in an M-file. This ca
Function fieldnames - structure functions: The function fieldnames will return the names of the fields which are contained in the structure variable. >> pack_fields = fiel
Illustration of Sorting strings: To sort on the rows rather than second dimension should be specified. >> sort(words,2) ans = Hello Hdowy Hi Gbdeo
Binary Search: The binary search supposes that the vector has been sorted first. The algorithm is just similar to the way it works whenever looking for a name in a phone direc
Use of built-in colormaps: MATLAB has built-in colormaps, it is also possible to generate others by using combinations of any colors. For illustration, the following generates
Illustration of anonymous functions: Dissimilar functions stored in the M-files, when no argument is passed to an anonymous function, the parentheses should still be in the fu
