Hi,

I noticed strange behavior with interp1 in combination with 'nearest'.

x=[11:20']';
y=[1:10]';
interp1(x,y, x(2:end-1)+[0.5 -0.5], 'nearest')
ans =

    3    7
    2    6
    4    8
    3    7
    5    9
    4    8
    6   10
    5    9
Notice that the output is given in the first column instead of per row
I would expect:
ans =

    3    2
    4    3
    5    4
    6    5
    7    6
    8    7
    9    8
   10    9
my current workaround is:
interp1(x,y, x(2:end-1)+[0.5 -0.5], 'nearest')(:), 2,8)'

Cheers, 

Michiel
