Octave/MATLAB like interpolation routines

interpolation

The library implements interp1 function similar to Octave/MATLAB.

Example program

program example1

  use iso_fortran_env, only: real64
  use interpolation
  
  real(real64) :: x(5) = [1, 2, 3, 4, 5]
  real(real64) :: y(5) = [0, 1, 0, 1, 0]
  real(real64) :: xi, yi
  
  xi = 1.5
  yi = interp1(x, y, xi, method="pchip")
  
  print *, "Interpolated value is ", yi

end program example1

More examples can be found in example folder.
