If x is a row vector,
returns a scalar equal to the mean of the elements of x.
a row vector, with the same number of columns as x
containing the average of the corresponding columns of x.
The argument where x
is an integer, real, double-precision, or complex matrix.
If x is an integer matrix,
the return value is double-precision.
Otherwise, the return value has the same type as x
If in Mlmode
x = 1 : 3;
O-Matrix will reply
If you continue by entering
x = [x ; x+1];
