stdDevPop( ) MATH/Statistics menu stdDevPop(list[, freqlist]) ⇒ expression Returns the population standard deviation of the elements in list. Each freqlist element counts the number of consecutive occurrences of the corresponding element in list. Note: list must have at least two elements. In Radian angle and auto modes: stdDevPop({a,b,c}) ¸ stdDevPop({1,2,5,ë 6,3,ë 2}) ¸ stdDevPop({1.3,2.5,L6.4},{3,2,5}) ¸ stdDevPop(matrix1[, freqmatrix]) ⇒ matrix Returns a row vector of the population standard deviations of the columns in matrix1. Each freqmatrix element counts the number of consecutive occurrences of the corresponding element in matrix1. Note: matrix1 must have at least two rows. stdDevPop([[1,2,5][-3,0,1][.5,.7,3]]) ¸ stdDevPop([L1.2,5.3;2.5,7.3;6,L4],[4, 2;3,3;1,7]) ¸ StoGDB CATALOG StoGDB GDBvar Creates a Graph database (GDB) variable that contains the current: * Graphing mode * Y= functions * Window variables * Graph format settings 1- or 2-Graph setting (split screen and ratio settings if 2-Graph mode) Angle mode Real/complex mode * Initial conditions if Sequence or Diff Equations mode * Table flags * tblStart, @tbl, tblInput You can use RclGDB GDBvar to restore the graph environment. *Note: These items are saved for both graphs in 2-Graph mode. 882 Appendix A: Functions and Instructions
