BldData CATALOG BldData [dataVar] In function graphing mode and Radian angle mode: Creates data variable dataVar based on the 8ùsin(x)!y1(x) ¸ Done information used to plot the current graph. 2ùsin(x)!y2(x) ¸ Done BldData is valid in all graphing modes. ZoomStd ¸ If dataVar is omitted, the data is stored in the system variable sysData. Note: The first time you start the Data/Matrix Editor after using BldData, dataVar or sysData (depending on the argument you used with BldData) is set as the current data variable. The incremental values used for any independent variables (x in the example to the right) are ¥ " calculated according to the Window variable BldData ¸ Done values. O 6 ¸ For information about the increments used to evaluate a graph, refer to the module that describes that graphing mode. 3D graphing mode has two independent variables. In the sample data to the right, notice that x remains constant as y increments through its range of values. Then, x increments to its next value and y again increments through its range. This pattern continues until x has incremented through its range. Note: The following sample data is from a 3D graph. ceiling( ) MATH/Number menu ceiling(expression1) ⇒ integer ceiling(0.456) ¸ 1. Returns the nearest integer that is , the argument. The argument can be a real or a complex number. Note: See also floor(). ceiling(list1) ⇒ list ceiling(matrix1) ⇒ matrix ceiling({ë3.1,1,2.5}) ¸ {ë3. 1 3.} Returns a list or matrix of the ceiling of each element. ceiling([0,ë3.2i;1.3,4]) ¸ [20. ë34.øi] Appendix A: Functions and Instructions 789
