Purpose

Outputs a double sigmoid function.


Synopsis

[y,y1,y2] = peaksigmoid(x,p)

Inputs

  • x = 5 element vector where
  • x(1) = coefficient,
  • x(2) = offset (left),
  • x(3) = decay constant (left),
  • x(4) = offset (right),
  • x(5) = decay constant (right).
Note: if length(x)==4 then x(5)=x(3) providing a symmetric double sigmoid.
  • p = axis 1xN (# of independent variables)

Outputs

  • y(1) = where and , 1xN
  • y(2) = , 3xN
  • y(3) = , 3x3xN
