chop()

Replace numbers in x with magnitude less than dx with 0

Syntax
y = chop(x, dx)

Arguments

Name	Description	Range	Type	Required
x	numbers to replace	(-∞, ∞)	integer, real, complex	yes
dx	value to compare to	(-∞, ∞)	integer, real, complex	yes

Examples

chop(1)
returns 1
chop(1e-12)
returns 0
chop(1+1e-12i)
returns 1+0i

Notes/Equations

The chop() function acts independently on the real and complex components of x, comparing each to mag(dx). For example,
y = x if mag(x) >= mag(dx)
y = 0 if mag(x)
