Number to indicate thickness. 1 is the most thin, and 4 is the thickest. |

Number of vectors to plot.The total number of nodes in the problem is divided by the number of desired vectors (this number) to get a stride. This stride is used to stride through the coordinate arrays to pick out points to put vectors on. |
|||
Magnification scale. A multiplier for manipulating the vector length. |

The vec command sets the options used when generating a vector plot. Note that this command does not change existing vector plots, only future ones. The variable read by the vector plot is a special merged multi-value variable which may be created with the defvar command.
