push_stddev

Declaration: void push_stddev (EStackIndex mat_lst_idx )
Category(ies): Lists and Matrices, Statistics, Math

pushes the standard deviation of the elements onto the estack. For a
matrix pushes a row vector containing the standard deviations of the matrix
columns.
Inputs: mat_lst_idx — Indexes the input matrix or list.
Outputs: None
Assumptions: None
Side Effects: May expand expression stack, cause heap compression, or throw an error.
