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 computations:
>> calccircum1(3.3)
20.7345
As no value is returned by the function, it would be an error to attempt to store the value in a variable:
>> c = calccircum1(3.3)
??? Error using ==> calccircum1
Too many output arguments.
By dissimilarity, the function below computes and returns the circumference, and hence, it can stored and used in other computations. For illustration, if the circle is the base of a cylinder, and we wish to compute the surface area of the cylinder, we would require to multiply the result from the calccircum2 function by the height of the cylinder.
>> circumference = calccircum2(3.3)
circumference =
>> height = 4;
>> surf_area = circumference * height
surf_area =
82.9380
Example of sorting strings: To sort a cell array of strings, also the sort function is used. The illustration is as follows, >> engcellnames = {'Chemical','Mechanical',.
Representing Logical true and False: It has been stated that expressions which are theoretically true really have the integer value of 1, and expressions which are theoretical
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
Reading from Files: There are many lower level functions which read from files. The function fscanf reads the formatted data into a matrix, by using conversion formats like %s
Polynomials: Simple curves are polynomials of various degrees, or orders. The degree is the integer of the highest exponent in the expression. The illustrations are as follows
#qYou will need to examine two of the nine sections of data: one section of qualitative data (choose either Gender or Position) one section of quantitative data (choose either Intr
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
function sortrows - sorting strings: The function sortrows sorts each and every row as a block, or group, and it also will work on numbers. Here in this illustration the rows
Functions which return Values versus printing: Also, the function which computes and returns values (throughout the output arguments) does not generally print them; that is le
Functions which complete a task without returning Values: Most of the functions do not compute values, but instead of accomplish a task like printing formatted output. As thes
