[proFit-list] Dynamically Adding Variables

[Kurt Sutter]

Dear Frederic

Please apologise the belated reply, I was on holidays.

Anyway, you can also do that in Python using *args parameters, which are basically placeholder for a variable number of arguments. In Python, the same thing would look as follows:


## function MyPoly

## input 0, constant, 'deg'
## input 1, inactive, 'a0'

def MyPoly_check(pNumber, *a):
    if pNumber == 1:    # if a[0] has changed
        if a[0] < 1 or a[0] > 100:
            return 2        # reject parameter change
        pf.GetFunctionObject(function = '').nrParams = a[0] + 1
        for i in range(0, int(a[0])+ 1):
            pf.GetParameterObject(parameter = i+1).name = 'a' + str(i)
        return 0            # update parameter window
    return 1                # return 1 if the parameter is fine

def MyPoly(x, deg, *a):
    y = 0
    for i in range(0, int(deg)):
        y = x * y + a[i]
    return y



Hope this helps
