Mean of matrix

 

mmean(A, n), perform the mean valueon the nthdimension of matrixA

A

1

[[1,0,2,3],[0,71,5,6],[0,0,6,5],[35,53,2,3],[35,8,4,2]]

2

=mmean(A1,1)

3

=mmean(A1,2)

4

=mmean@a(A1)

A1 Input a matrix with 5 vector members

..

A2 n=1, calculate mean valueon the matrix’s first dimension layer, counterpoint mean of the vector members.That is, calculate mean value on membersof each column.

..

A3 n=2, calculatemeanon the matrix’s seconddimension layer, mean value on the elements within each vector. That is, calculate meanon members of each row.

..

A4 Calculatethe mean value of all elements inA1
