Variable packages:
Variable packages are now the vector of structures, hence each and every element in the vector is a structure. To show one element in the vector, an index into the vector would be identified. For illustration, to refer to the second element:
>> packages(2)
ans =
item_no: 456
c ost: 5.9900
price: 49.9900
code: 'l'
To refer to the field, it is essential to refer to the specific structure, and then the field within it. This means that using an index into the vector to refer to the structure, and then the dot operator to refer the field. For illustration:
>> packages(1).code
g
Hence, there are necessarily three levels to this data structure. The variable packages are at highest level that is a vector of structures. Each of its elements is a separate structure. The fields within these individual structures are at lowest level. The loop below displays each element in the packages vector.
>> for i = 1:length(packages)
disp(packages(i))
end
item_no: 123
cost: 19.9900
price: 39.9500
code: 'g'
cost: 5.9900
item_no: 587
cost: 11.1100
price: 33.3300
code: 'w'
To refer to a specific field for all structures, in most of the programming languages it would be essential to loop through all the elements in vector and use the dot operator to refer to the field for each element. Though, this is not the case of MATLAB.
Graphics objects: The objects involve graphics primitives like lines and text, and also the axes used to orient the objects. These objects are organized hierarchically, and the
Generic code for Reading from Files: The generic code to complete this is as shown below: fid = fopen('filename'); if fid == -1 disp('File open not suc
Data structure layers: There are many layers in this variable. For illustration, cyls is the whole data structure, that is a vector of structs cyls(1) is a separate
Illustration of Indexing: Though, rather than of creating the index vector manually as shown here, the process to initialize the index vector is use to a sort function. The al
Illustration of Input in a for loop: In this illustration, the loop variable iv iterates through the values 1 through 3, therefore the action is repeated three times. The acti
Function Stubs: The other common debugging method, which is used when there is a script main program which calls many functions, is to use the function stubs. A function stub
Combining Nested FOR Loops and the IF Statements: The statements inside a nested loop can be any of the valid statement, involving any selection statement. For e.g., there can
Illustration of reading from files: For illustration, suppose that there is a data file 'subjexp.dat' that has on each line a number followed by thecharacter code. The type fu
Sorting Strings: For the matrix of strings, the sort function works exactly as formerly for numbers. For illustration, >> words = char('Hi', 'Hello', 'Howdy', 'Goodbye', '
Rectangle - graphics objects: The other core graphics object is the rectangle that can have curvature added to it (!!). Merely calling the function rectangle without any argum
