The following commands perform various operations on vectors, which are the basic data structures of WRspice. Vectors from the current plot can be referenced by name. A listing of the vectors for the current plot is obtained by typing the let or display commands without arguments, or pressing the Vectors button in the Tools menu. Vectors for other than the current plot are referenced by plotname.vecname, for example, tran2.v(1). The current plot can be changed with the setplot command, or from the panel brought up by the Plots button in the Tools menu. See 3.16 for more information about vectors.
Vectors can be created and manipulated in many ways. For example, typing
let diff = v(1) - v(2)creates a new vector diff. All vectors can be printed, plotted, or used in expressions. They can be deleted with the unlet command.
