7 Controlling Plot Features from within the Input Data File In addition to type and color, D_2D allows marker occurrence to be controlled from within the data file, that is, they can be turned off and back on. However, their style cannot be set or changed, say from ‘***’ to ‘‐*‐’ or ‘*#*’, and a line without markers cannot be turned into a line with markers from within the data file. Important: You will have to assign some type of markers to your graph from within D_2D in order for the input data file control lines to have an effect.

CF2. increase the sampling rate around them. Remember that for 400 data points, the singular points were not detected. 12b indicates, the singular points of F(x) coincide with the roots of equation 1/F(x) = 0. The data files needed to generate this last figure were produced with P1_12B. PAS, where function F was replaced with 1/F. 7 Controlling Plot Features from within the Input Data File In addition to type and color, D_2D allows marker occurrence to be controlled from within the data file, that is, they can be turned off and back on.

PAS listed in Appendix B. Before the actual function is evaluated, the program checks whether x is almost equal to −2 or +2 (see line #14 of the source code), and if found true, then the function is assigned the constant InfD defined in unit LibMath, which is equal to 10100. Constant EpsD, defined in the same unit LibMath, is a very small positive number set equal to 10−100. ), is used to code additional information about the input data or of the state of the procedure from where the value originates.
