tri
Computes a triangular pulse centered at zero.
tri(x) returns 1-|x| when |x|<1 and 0 when |x|>=1. Unresolved symbolic inputs remain as tri(x).
Examples
These examples use Nerdamer Notation.
Evaluate the peak of the triangular pulse.
tri(0)
// → 1Evaluate an interior point exactly.
tri(1/4)
// → 3/4Return zero at the boundary.
tri(1)
// → 0Keep an unresolved symbolic input unevaluated.
tri(x)
// → tri(x)Interfaces
