Histogram:
The histogram is a particular type of bar chart which shows the frequency of occurrence of the values within a vector. The Histograms use what are known as bins to collect values which are in given ranges. The MATLAB has a function to generate a histogram, hist. Calling the function with the form hist(vec) by default take the values in the vector vec and place them into 10 bins (or, hist(vec,n) will place them in n bins) and plots this, which is as shown in figure.
>> vec = randint(1,12,[1 10])
vec =
10 8 2 5 10 10 5 9 1 4 9 1
>> hist(vec)
In this illustration, the numbers range from 1 to 10 in the vector, therefore there are 10 bins in the range from 1 to 10. The heights of the bins present the number of values which fall within that specific bin. The hist function really returns values; the first returned is a vector showing how many of the values from the original vector fall in each of the bins:
>> c = hist(vec)
c =
2 1 0 1 2 0 0 1 2 3
The bins in a histogram are not essentially all of similar width. The Histograms are used for statistical analyses on data.
Program of built-in factorial function: Calling this function yields similar result as the built-in factorial function: >> fact(5) ans = 120 >> factorial(
Example of Recursive functions: This definition is recursive as a factorial is defined in terms of the other factorial. There are two parts to any recursive definition: the co
Example of Minimum and Maximum Value For matrices, the functions min and max operate column wise by the default: >> mat = randint(2,4,[1 20]) mat = 9 10 1
Functions to create special matrices: The MATLAB also has various functions which create special matrices. For illustration, the zeros function generates a matrix of all zeros
sprintf function: The sprintf function works precisely like the fprintf function, but rather than printing it generates a string. Here are some illustrations in which the outp
Script a MATLAB program which meets the following speci cations: The program expects an input of a two-variable real-valued continuous function f : R^2--> R The program is to cal
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 pe
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
Illustration of Standard Deviation The less spread out the numbers are, therefore smaller the standard deviation will be, as it is a way of determining the spread of the data.
Strings as matrix: The matrix can be generated, that consists of strings in each row. Therefore, essentially it is created as a column vector of strings, but the final result
