TopMethods Remarks A parameterized functional
defines a funtion mapping a vector to a real value for each set of parameters. For example:
f(x1, x2: a, b) = a*cos(b*x1) + b*sin(a*x2)
is a parameterized function. For each set of values, a and b, it defines
a function of x1, x2. For example if a = 1 and b = 2 then
f(x1, x2) = cos(2*x1) + 2*sin(x2)
Parameterized function are used by curve fitting routines and solve the
following problem -
Suppose I have a set of points (xi, yi), i = 1...n, and I want to determine
the values of a and b in the above parameterized function f(x1, x2: a, b) described
above so that f fits the data points.
