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 =

Generic code for Reading from Files: The generic code to complete this is as shown below: fid = fopen('filename'); if fid == -1 disp('File open not suc
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
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
Vectorizing: In most of the cases in MATLAB, loops are not essential. As MATLAB is written specifically to work with the vectors and matrices, most operations can be completed
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
Illustrations of Sequential search: The two illustrations of calling such function is as shown below: >> values = [85 70 100 95 80 91]; >> key = 95; >> seqsearch
bjjh
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
Median The median is defined only for a data set which has been sorted first, that means that the values are in order. The median of a sorted set of data values (n) is defined
Sorting Strings: For the matrix of strings, the sort function works exactly as formerly for numbers. For illustration, >> words = char('Hi', 'Hello', 'Howdy', 'Goodbye', '
