Standard deviation of matrix

mstd(A, n), perform the standard deviation on the n^th 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.
