-    This is generator of CLapack subset.
-    The usage:
-
-    1. Make sure you have the special version of f2c installed.
-       Grab it from https://github.com/vpisarev/f2c/tree/for_lapack.
-    2. Download fresh version of Lapack from
-       https://github.com/Reference-LAPACK/lapack.
-       You may choose some specific version or the latest snapshot.
-    3. If necessary, edit "roots" and "banlist" variables in this script, specify the needed and unneeded functions
-    4. From within a working directory run
-
-       $ python3 <opencv_root>/3rdparty/clapack/make_clapack.py <lapack_root>
-       or
-       $ F2C=<path_to_custom_f2c> python3 <opencv_root>/3rdparty/clapack/make_clapack.py <lapack_root>
-
-       it will generate "new_clapack" directory with "include" and "src" subdirectories.
-    5. erase opencv/3rdparty/clapack/src and replace it with new_clapack/src.
-    6. copy new_clapack/include/lapack.h to opencv/3rdparty/clapack/include.
-    7. optionally, edit opencv/3rdparty/clapack/CMakeLists.txt and update CLAPACK_VERSION as needed.
-
-    This is it. Now build it and enjoy.

-//> DLAISNAN checks for NaNs by comparing its two arguments for
-//> inequality.  NaN is the only floating-point value where NaN != NaN
-//> returns .TRUE.  To check for NaNs, pass the same variable as both
-//> arguments.
-//>
-//> A compiler must assume that the two arguments are
-//> not the same variable, and the test will not be optimized away.
-//> Interprocedural or whole-program optimization may delete this
-//> test.  The ISNAN functions will be replaced by the correct
-//> Fortran 03 intrinsic once the intrinsic is widely available.
