**Example User Defined Functions** C * exp(2.2/X) + 51.0 + pi ** e - sinc(1.1) / [B + A] # coefficients are A, B and C |

Scale * exp(X) + offset # Scale and offset are coefficents in this example |

# the following three examples are equivalent
power(X+shift, C0) # shift and C0 are coefficients in this example
[X+shift] ** C0 # shift and C0 are coefficients in this example
(X+shift) ** C0 # shift and C0 are coefficients in this example |

MX + B # This fails, it should be written as M*X + B |
