mean - mean (row mean, column mean) of vector/matrix entries

Calling Sequence

y=mean(x)

y=mean(x,'r')

y=mean(x,'c')

Parameters

• x : real vector or matrix
• y : scalar or vector

Description

For a vector or a matrix x , y=mean(x) returns in the scalar y the mean of all the entries of x .

y=mean(x,'r') (or, equivalently, y=mean(x,1) ) is the rowwise mean. It returns a row vector: y(j)= mean(x(:,j))

y=mean(x,'c') (or, equivalently, y=mean(x,2) ) is the columnwise mean. It returns a column vector: y(i)= mean(x(i,:))

Examples

A=[1,2,10;7,7.1,7.01];
mean(A)
mean(A,'r')
mean(A,'c')
