Use of Nested if-else statements:
By using the nested if-else to select from among the three possibilities, not all the conditions should be tested. In this situation, if x is less than -1, the statement is assign 1 to y is then executed, and the if-else statement is done so no other conditions are tested. If, though, x is not less than -1, then the else clause is executed. When the else clause is executed, then we know that x is greater than or equal to -1 so that section does not require to be tested. Rather than that, there are only two remaining possibilities: either x is less than or equal to 2, or it is bigger than 2. An if-else statement is used to select between those two possibilities. Therefore, the action of the else clause was the other if-else statement. Though it is long, this is one if-else statement, and a nested if-else statement. The actions are indented to represent the structure.
Nesting if-else statements in such a way that it can be used to select from among three, four, five, or more options-the possibilities are practically endless!
This is really an illustration of a particular type of nested if-else known as cascading if-else statement. In this category of nested if-else statement, the conditions and actions cascade in the stair-like pattern.
num2str function: The num2str function, that converts real numbers, can be called in many ways. If only the real number is passed to the num2str function, it will generate a s
Displaying expressions: The good-looking function will show such expressions by using exponents; for illustration, >> b = sym('x^2') b = x^2 >> pretty(b)
Illustration of Variable scope: Running this function does not add any of variables to the workspace, as elaborated: >> clear >> who >> disp(mysum([5 9 1]))
Illustration of Vectors of structures: In this illustration, the packages are vector which has three elements. It is shown as a column vector. Each and every element is a stru
Defined a variable in work space: The variables defined in the script will become a part of the workspace: >> clear >> who >> mysummfile 15 >> who
. Generate the following signal, x(n)=1+cos((25*pi*n)/100),0 Compute the DTFT of x[n] for w=0:0.01:2*pi Plot the Real part, imaginary part, the amplitude and phas
function imread: The function imread can read an image file, for illustration a JPEG (.jpg) file. The function reads color images into a 3-dimensional matrix. >> myimage1
Replacement : Replace a row by adding it to (or subtract from it) a multiple of the other row. For a given row ri, this is written as ri - srj → ri Note that when r
