mex c++ interface to call Eureqa server directly from matlab The code enables symbolic regression with possible user-defined operators (such as +, -, *, /, ^, exp, log, sin, cos, abs, tan). Applications range from a detection of hidden data relationships to nonlinear regression of different kinds to feature selection for machine learning algorithms.
Numerical integration from -Inf to Inf of an integrand in the form f(x)*exp(-x^2)
f(x) must be a slowly varying function
fn_val = GaussHermite(func, npt, varargin)
func is a handle for f(x)
npt is the...
Syntax::::power2(a,b) where, a=base b=exponent
Matlab function power's result if more than 9 digits,give the result as in exp.(e) terms.This power2 gives the result to as much digits as is the exact answer.
[sigma,mu,A]=mygaussfit(x,y) [sigma,mu,A]=mygaussfit(x,y,h)
this function is doing fit to the function y=A * exp( -(x-mu)^2 / (2*sigma^2) )
the fitting is been done by a polyfit the lan of the data.
Evaluate integrals of this form:
-inf int +inf f(x)exp(-(x-mu)/2sigma^2)
where f(x) is a smooth function.
Computes the Gaussian function in 1D: exp(-log(2)*(2*(x-x0)./FWHM).^(2*floor(abs(order))));
Where: x = Co-ordinate x0 = Centre of function FWHM = Full Width Half Max of the function order = Gaussian order
high accuracy version of log(sum(exp(x)))
