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 starting with 3 and 4 are placed first then, for the rows starting with 5, the values in the second column (6 and7) determine the order.
>> mat = [5 7 2; 4 6 7; 3 4 1; 5 6 2]
mat =
5 7 2
4 6 7
3 4 1
5 6 2
>> sortrows(mat)
ans =
Sorting Strings: For the matrix of strings, the sort function works exactly as formerly for numbers. For illustration, >> words = char('Hi', 'Hello', 'Howdy', 'Goodbye', '

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];
Example of Median For the vector [1 4 5 9 12 33], the median is the average of the 5 & 9 in the middle: >> median([1 4 5 9 12 33]) ans = 7
Example of customizing plots: As the other illustration of customizing plots, the pieces of a pie chart can be "exploded" from the rest. In this situation, the two vectors are
