"WebJul 25, 2014 · In Fortran this is not the case. You only get to have one place within a Link output where you can define the type. Note "within a Link output". A DLL and an application will have it defined in different places (but most likely within the same module). Some distros may have different declarations (but functionally useful to the application) to ... " - Bspline fortran

WebAug 21, 2024 · The specifications of bspline-fortran seem to indicate that the interpolation works for structured, rectilinear, stretched grids, so I suppose that this is the definition of 'regular' grid in your case. The good news is that your grid is 'regular' by that definition. WebBspline¶. The bspline function return the value at x in [0,1[ of the B-spline with integer nodes of degree p with support starting at j. Implemented recursively using the de Boor’s recursion formula.

The library provides subroutines for 1D-6D interpolation and extrapolation using B-splines. The code is written in modern Fortran (i.e., Fortran 2003+). There are two ways to use the module, via a basic subroutine interface and an object-oriented interface. Both are thread safe. See more The core routines for the subroutine interface are: The ink routines compute the interpolant coefficients, and the val routines evalute the … See more In addition to the main subroutines, an object-oriented interface is also provided. For example, for the 3D case: Which uses the default "not-a-knot" end conditions. You can also specify … See more The library also contains routines for computing definite integrals of bsplines. There are two methods (currently only for 1D): 1. Basic version: db1sqad (integral in the object-oriented interface) -- Computes the integral on … See more The library optionally supports extrapolation for points outside the range of the coefficients. This is disabled by default (in which case an error code is returned for points outside the bounds).

WebCubic spline interpolation in Fortran. A module for cubic spline interpolation in Fortran, based on: spline.f; spline.f90, a Fortran 90 translation of spline.f; Requirements. A somewhat recent Fortran compiler (gfortran is the default compiler in the Makefile). Usage. Usage looks like this: Webprivate pure function get_bspline_status_message (me, iflag) result (msg) Get the status message from a bspline_class routine call. If iflag is not included, then the one in the class is used (which corresponds to the last routine called.) Otherwise, it will convert the input iflag argument into the appropriate message.
