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 =

Vectors of nested structures: The Combining vectors and nested structures are possible to have a vector of structures in which several fields are structures themselves. Here i
Illustration of Nested loops: Running the script shows the output: >> printstars ***** ***** ***** The variable rows identifies the number of rows to print, and
Help function: Function is computing the two values, there are two output arguments in the function header (i.e., area & circum), that are placed in the square brackets [ ]. A
Sequential Search: A sequential search is completed by looping through the vector element-by-element starting from the beginning, looking for the key. Usually the index of the
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
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
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
Steps for input output functions - Lower level file: The steps involved are as shown below: Open the file. Read the file, write to the file, or append to the file.
Use of function polyval: The better the curve fit, the more exact these interpolated and extrapolated values will be. By using the subplot function, we can loop to display the
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
