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.
Use of logical vector: Determine how many elements in the vector vec were greater than 5, the sum function can be used on the resulting vector isg: >> sum(isg) ans =
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
Plot types: Besides plot and bar, there are another plot types like stem plots, histograms, stem plots, area plots and pie charts, and also other functions which customize the
Find Minimum and Maximum for each row To find the maximum (or minimum) for each row, the dimension of 2 (that is how a MATLAB refers to rows) can be identified as the third arg
Function xlsread - file function: The function xlsread will read from the spreadsheet file. For illustration, to read from file just generated: >> ssnums = xlsread('ranexc
How do I write a product series running from i to n of x''s using a for loop?
Illustration of Variance For illustration, for the vector [4, 6, 1, 5], there are n = 4 values therefore n - 1 is 3. The mean of this data set is also 4. The variance will be
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,
Illustration of Logical vectors: Calling the function appears to return similar vector as simply vec > 5, and summing the result still works to determine how many elements wer
The variance is generally defined in terms of the arithmetic mean as: At times, though, the denominator is defined as n instead of n - 1. The default definition used by t
