Standard deviation of matrix

 

mstd(A, n), perform the standard deviation on the nth dimension of matrix A

A

1

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

2

=mstd(A1,1)

3

=mstd(A1,2)

4

=mstd@s(A1,2)

A1 Input a matrix with 5 vector members

..

A2 n=1, calculate standard deviation on the matrix’s first dimension layer, counterpoint standard deviation of the vector members. That is, calculate standard deviation on members of each column.

..

A3 n=2, calculate standard deviation on the matrix’s second dimension layer, standard deviation on the elements within each vector. That is, calculate standard deviation on members of each row.

..

A4 Perform the calculation using the statistical method
