numpy.isfortran(array) : This is a logical function that checks whether array is Fortran contiguous or not.
Order : [C-contiguous, F-contiguous, A-contiguous; optional]
C-contiguous order in memory(last index varies the fastest). C order means that operating row-rise on the array will be slightly quicker.
FORTRAN-contiguous order in memory (first index varies the fastest). F order means that column-wise operations will be faster.
‘A’ means to read / write the elements in Fortran-like index order if, array is Fortran contiguous in memory, C-like order otherwise.
array : [array_like]Input array
True, if array is Fortran; else False
Code 1 :
Input array : [[1 2 3] [4 5 6]] isfortran : False
Code 2 :
Input array : [[1 2 3] [4 5 6]] isfortran : True
