Mean or typical is the average the a sequence of numbers. In MATLAB, mean (A) return the typical of the materials of A along the first array dimension whose size doesn’t same to 1. Mean that A is a vector, climate mean(A) return the mean of the components. Now, if A is a matrix form, climate mean(A) returns a row vector containing the mean of every column.

Mean =\displaystyle \bar x=\frac 1n\left(\sum _i=1^nx_i\right)=\frac x_1+x_2+\cdots +x_nn Example:Mean of succession x = <1,2,3,4,5> = sum of numbers/Count of numbers = 15/5 = 3


Different syntax of the mean() technique is:M = mean(A)M = mean(A,’all’)M = mean(A,dim)M = mean(A,vecdim)

M = mean(A)

It return the mean of succession A.If A is a vector, climate it returns the typical of all aspects in the vectorIf A is a matrix, climate it returns a vector whereby each element is the average of each obelisk in A.Example:
Output:


Output :

M = mean(A, ‘all’)

It return the mean of all the elements in A one of two people it deserve to be vector or matrix.Example:

M = mean(A,dim)

It returns the mean of procession A follow me each of the offered dim.If dim = 1, climate it return a vector where the average of each column is included.If dim = 2, then it return a vector where the median of each row is included.

Example:
Output :

M = mean(A,vecdim)

It return the mean of A based on the stated dimensions vecdim in A.If A is a 2-by-2-by-3 array, then mean(A,<1 2>) calculates the average of each page of dimension 2-by-2 together it’s thought about as a solitary entity. Therefore it return the vector of dimension 3 as the average of every page.Example:
