Pie chart - plot functions:
The MATLAB also has a function pie which will generate a pie chart. Calling the function with the form pie (vec) draws a pie chart, by using the percentage of each element of vec of the entire (the sum). It shows these beginning from the top of the circle and going around counter-clockwise. For illustration, the first value in the vector [3 10 5 2] , 3, is 15% of the sum, 10 is 50% of the sum, and so on, as shown in figure.
>> pie ([3 10 5 2])
Also a cell array of labels can be passed to the pie function; such labels will appear rather than the percentages as shown in figure.
>> pie([3 10 5 2], {'A','B','C','D'})
Example of Symbolic Expression When there is more than one variable, the MATLAB selects which to solve for. In the illustration below, the equation ax 2 + bx = 0 is solved. Th
strvcat function - concatenation: The function strvcat will concatenate it vertically, that means that it will generate a column vector of the strings. >> strvcat(fir
bar and barh functions: For a matrix, the bar and barh functions will group altogether the values in each and every row. The illustration is as shown: rm = randint(2,4,[1
Illustration of Writing variables to a file: For illustration, in the below session in the Command Window, 3 variables are generated; these are then exhibited using who. Then,
Applications of Customized Strings: Labels, Prompts, Arguments to Functions: The one of very useful application of this is to involve numbers in strings that are used to plot
Indexed empty matrix: The Individual elements cannot be eliminated from matrices, as matrices always have the similar number of elements in every row. >> mat = [7 9 8; 4 6
Animation: In this part we will observe a couple of ways to animate a plot. These are visuals, therefore the outcomes can't really be shown here; it is essential to type these
User input in the while loop: Here is an illustration of running this script: >> readonenum Enter a positive number: -5 Invalid! Enter a positive number: -2.2
Illustration of Advanced file input and output: For illustration, to refer to the third number in the first element of the cell array: >> subjdata{1}(3) ans =
