'''Description'''
'''Description'''


Numerically integrate given data by Simpson method. Program reads three numbers from input file (x coordinate, derivative, and standard deviation of derivative). As output program prints copy of input data plus integrated values and its standard error.
<p style="text-indent: 1em; text-align: justify;">The program numerically integrates data from the PMF calculations. The integration is performed either by the reverse finite difference (RFD) method, radial basis functions (RBF), or Gaussian process (GPR).</p>
