interpolation - Why is Matlab function interpn being modified? -


the matlab function interpn n-grid interpolation. according documentation page:

in future release, interpn not accept mixed combinations of row , column vectors sample , query grids.

this page provides bit more information still kind of cryptic.

my question this: why modification being implemented? in particular, there pitfalls using interpn?

i writing program in fortran supposed produce similar results matlab program uses interpn crucial component. i'm wondering if matlab program might have problem related modification.

no, don't think indicates there sort of problem using interpn, or of other matlab interpolation functions.

over last few releases mathworks has been introducing new/better functionality interpolation (for example griddedinterpolant, scatteredinterpolant , delaunaytriangulation classes). has been going on in small steps since r2009a, when replaced underlying qhull libraries computational geometry cgal.

it seems me interpn has long time supported unusual form of input arguments (i.e. mixed row , column vectors define sample grid) bit confusing people, hardly ever used, , bit of pain mathworks support. move forward newer functionality, they're taking opportunity simplify of syntaxes supported: doesn't mean there problem interpn.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
