Extended Definition
The following equation defines SHF:
STEP
STEP approximates a step function with a cubic polynomial.
Use
Called By
Any user-written subroutine
Welcome to Adams/Solver Subroutines
x A double-precision variable that specifies the independent variable.
x0 A double-precision variable that specifies a shift in the independent variable.
a A double-precision variable that specifies the amplitude of the harmonic
function.
w A double-precision variable that specifies the frequency of the sine function.
The variable must be in radians per unit of the independent variable.
phi A double-precision variable that specifies a phase shift in the sine function.
The variable phi must be in radians.
b A double-precision variable that specifies the average value of displacement.
iord An integer variable that defines the order of the derivative that SHF is to
return. The order is usually zero, but it can be one or two.
errflg A logical (true or false) variable that SHF returns to the calling subroutine.
If SHF detects an error in the subroutine call statement, it sets errflg to true
before it returns errflg to the calling subroutine.
value A double-precision value the subroutine returns. The value returned
depends on IORD as follows
a ⋅sin
( w ⋅(
x – x0) – φ ) + b
