Matrices - Using Statistical Operations

Calculating Statistics of Vectors
MATLAB contains many functions that you can use to calculate statistics of vectors. Some of the most common functions include:
Generally, statistical analysis functions in MATLAB work on each column of a matrix independently.
The min and max functions can be used with two outputs. The second output is the index (location) of the maximum or minimum value.
You can use the sort function to sort the values of a vector. By default, the values are sorted in ascending order.
Descriptive Statistics
Generally, statistical analysis functions in MATLAB work on each column of a matrix independently.
1.
Create a row vector named xAvg which contains the average value of each column x.
2.
Create a row vector named xMax which contains the maximum value of each column of x.
3.
Create a row vector named xSum. For each column in x, sum the elements in that column together.
Statistics for Each Row
Many statistical functions accept an optional dimensional argument that specifies whether the operation should be applied to the columns independently (the default) or to the rows.
The following command calculates the mean of each row of A.
mean(A,2)
In the min, max, and diff functions, the third input is reserved for the dimension to operate along. To skip defining the second input value, use an empty array, [].
minRowElement = min(M,[],2);
