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.
Finding a sting - function findstr: The function findstr receives two strings as input arguments. It finds all the occurrences of shorter string contained by the longer, and r
Function fieldnames - structure functions: The function fieldnames will return the names of the fields which are contained in the structure variable. >> pack_fields = fiel
Vector operations: As vectors are special cases of matrices, the matrix operations elaborated (addition, subtraction, multiplication, scalar multiplication, transpose) work on
Set Operations: The MATLAB has numerous built-in functions which perform set operations on vectors. These involve intersect, union, setdiff, unique, and setxor. All these func
Matrix solutions to systems of the linear algebraic equations: The linear algebraic equation is an equation of the form a 1 x 1 + a 2 x 2 + a 3 x 3 . . . . a n x n
Function call: In the function call, not any arguments are passed so there are no input arguments in the function header. The function returns an output argument, therefore th
Technique to create Nested structures: This technique is the most proficient. Though, the other technique is to build the nested structure one field at a time. As this is a ne
Gauss-Jordan: The Gauss-Jordan elimination technique begins in similar way which the Gauss elimination technique does, but then rather than of back-substitution, the eliminati
Example of Gauss-jordan: For a 2×2 system, this would results and for a 3 × 3 system, Note that the resulting diagonal form does not involve the right-most col
Illustration of Subfunctions: This is an illustration of running this program: >> rectarea Please enter the length: 6 Please enter the width: 3 For a rectan
