hi all. I have some data and I want to interpolate z in this data. I used this code:
% year2012=xlsread('year2012');
year2012=double(year2012);
X=year2012(1:91,1);
Y=year2012(1:91,2);
Z=year2012(1:91,3);
x=year2012(1:91,4);
y=year2012(1:91,5);
z = interp2(X,Y,Z,x,y);
but I have this error :
% Error using griddedInterpolant
The coordinates of the input points must be finite values; Inf and NaN are not permitted.
Error in interp2>makegriddedinterp (line 228)
F = griddedInterpolant(varargin{:});
Error in interp2 (line 128)
F = makegriddedinterp({X, Y}, V, method,extrap);
Error in new (line 19)
z = interp2(X,Y,Z,x,y,'nearest');code
I attached my data and I think my data is true. can you please guide me?
