HP Prime Graphing NW280AAABA manual Sto Stores a real or string in a variable

stddevp Returns the population standard deviation of the elements of a list or a list of the population standard deviations of the columns of a matrix. The optional second list is a list of weights.

stddevp(List1, [List2]) or stddevp(Vector1, [Vector2]) or stddevp(Matrix)

Example:

stddevp({1,2,3}) gives 1

sto Stores a real or string in a variable.

sto((Real or Str),Var)

sturmseq Returns the Sturm sequence for a polynomial or a rational fraction.

sturmseq(Poly,[Var])

Example:

sturmseq(x^3-1,x) gives [1 [[1 0 0 -1] [3 0 0] 9] 1]

subMat Extracts from a matrix a sub matrix whose diagonal is defined by four integers. The first two integers define the row and column of the first element and the last two integers define the row and column of the last element of the sub matrix.

subMat(Matrix, Int1, Int2, Int3, Int4)

Example:

⎛	1 2	⎞
⎜		⎟	returns
subMat ⎜	3 4	, 2, 1, 3, 2⎟
⎜	5 6	⎟
⎝		⎠
