r2 = rsquare(y,f)

RSQUARE computes the coefficient of determination (R-square) value from
actual data Y and model data F.

INPUTS
Y : Actual data
F : Model fit

OUTPUT
R2 : Coefficient of determination

EXAMPLE
x = 0:0.1:10;
y = 2.*x + 1 + randn(size(x));
p = polyfit(x,y,1);
f = polyval(p,x);
r2 = rsquare(y,f);
figure;...



a = lorentzfit1(x,y,a0)

LORENTZFIT1 fits the input Y(X) with a Lorentzian function of the form
Y'(X) = 1./(A(X.^2 + 1)) (i.e. 1-parameter model).

INPUTS
X : Independent variable values
Y : Dependent...



a = lorentzfit3(x,y,a0)

LORENTZFIT3 fits the input Y(X) with a Lorentzian function of the form
Y'(X) = A1./((X - A2).^2 + A3) (i.e. 3-parameter model).

INPUTS
X : Independent variable values
Y :...
