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 =

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];
Illustration of Customizing plots: Illustration, the bar and barh functions by the default place a width of 0.8 between bars. Whenever called as bar(x,y), the width of 0.8 is
Graphics objects: The objects involve graphics primitives like lines and text, and also the axes used to orient the objects. These objects are organized hierarchically, and the
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
Advanced File Input and output: Where 'format' involves the conversion characters much like those used in the fprintf function. For illustration, to read the file 'subjexp.dat
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
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
Editor/Debugger: The MATLAB has numerous useful functions for debugging, and debugging can also be completed through its editor, which is known as the Editor/Debugger. Typi
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
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
