.SH NAME
mean - mean (row mean, column mean) of vector/matrix entries
.SH CALLING SEQUENCE
.nf
y=mean(x)
y=mean(x,'r')
y=mean(x,'c')
.fi
.SH PARAMETERS
.TP 10
x
: real vector or matrix
.TP 10
y
: scalar or vector
.SH DESCRIPTION
For a vector or a matrix \fVx\fR, \fVy=mean(x)\fR returns in the
scalar \fVy\fR the mean of all the entries of \fVx\fR.
.LP
\fVy=mean(x,'r')\fR (or, equivalently, \fVy=mean(x,1)\fR) is the rowwise mean. It returns in each
entry of the column vector \fVy\fR the mean of each row of \fVx\fR.
.LP
\fVy=mean(x,'c')\fR (or, equivalently, \fVy=mean(x,2)\fR) is the columnwise mean. It returns in each entry of the row vector
\fVy\fR the mean of each column of \fVx\fR.
.SH EXAMPLE
.nf
A=[1,2,10;7,7.1,7.01];
mean(A)
mean(A,'r')
mean(A,'c')
