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 action holds of prompting the user for a number and echo printing it with one decimal place.
Rather than of simply echo-printing the numbers, it is frequently necessary to store them in a vector. The one way of accomplishing this is to begin by preallocating the vector and then putting the values in each element, as we saw in earlier example. Here is a function which does this, and returns the resulting vector. The function receives input argument n, and repeats the procedure n times.
Here is an illustration of calling this function and storing the resulting vector in a variable known as the myvec.
>> myvec = forinputvec(3)
Enter a number: 44
Enter a number: 2.3
Enter a number: 11
myvec =
44.0000 2.3000 11.0000
Nested for Loops: The action of a loop can be any of the valid statement(s). Whenever the action of a loop is the other loop, this is known as nested loop. As an illustrati
Illustration of Nested loops: Running the script shows the output: >> printstars ***** ***** ***** The variable rows identifies the number of rows to print, and
Illustration of Binary search: An illustration to search for the key of 91 in the vector is as shown below: The table below shows what will happen in each iteration of
Mode The mode of a data set is the value which appears most often. The built-in function in a MATLAB for this is known as the mode. >> x = [9 10 10 9 8 7 3 10 9 8 5 10];
Example of Nested functions: For illustration, the function below computes and returns the volume of a cube. Three arguments are then passed to it, for the width and length of
Areacirc function: The areacirc function can be called from the Command Window as shown here, or from a script. Here is a script which will prompt the user for the radius of o
Example of Mode When no value appears more often than any other, the smallest value in the vector will be the mode of the vector. >> shortx = [2 5 1 4]; >> mode(shortx
Example of Functions which return values: Calling this function prints the circumference, since there is no way to store the value, hence, it can be used in following computat
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 i
Index vector: The index vector is then used as the indices for original vector. To get grades vector in ascending order, the indices used would be grades (2), grades (5), and
