Before such routines could be called from Python but the +corresponding Fortran routines received assumed shape arrays as zero +length arrays which caused unpredicted results. Thanks to Lorenz +Hüdepohl for pointing out the correct way to interface routines with +assumed shape arrays. + +In addition, f2py interprets Fortran expression ``size(array, dim)`` +as ``shape(array, dim-1)`` which makes it possible to automatically +wrap Fortran routines that use two argument ``size`` function in +dimension specifications. Before users were forced to apply this +mapping manually. Other new functions |
