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 =

Nested Functions: We have seen that the loops can be nested, that means that one inside of the other, functions can be nested. The terminology for nested functions is that an
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
Persistent Variables: Generally, whenever a function stops executing, then the local variables from that function are cleared. That means that each and every time a function i
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
Sorting Strings: For the matrix of strings, the sort function works exactly as formerly for numbers. For illustration, >> words = char('Hi', 'Hello', 'Howdy', 'Goodbye', '
Statistics There are numerous statistical analyses which can be executed on data sets. In MATLAB software, the statistical functions are in the data analysis help topic known a
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
#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
Illustration of nested for loops and the if statements: For illustration,when the file contains: 33 -11 2 4 5 9 22 5 -7 2 11 3 the outco
WHILE Loops: The while statement is used as a conditional loop in MATLAB; it is used to repeat an action whenever ahead of the time it is not known how many times the action w
