Error using interp2, line226 and line126

size of Pressure=82*1, temperature=1*601, density=600*81

---------------------------------------------------------------------------------------------------------------------

for i=drange(1:100)

P=101;

result1=zeros(100);

result1(i)=interp2(Pressure,temperature,density,P,temperature(i));

disp(result1(i))

end

Error using interp2>makegriddedinterp (line 226)

Error using griddedInterpolant

Interpolation requires at least two sample points for each grid dimension.

Error in interp2 (line 126)

F = makegriddedinterp({X, Y}, V, method,extrap);

how to slove this griddedInterpolantion error?

[Chunru]

The sizes of data points are not compatible:

size of Pressure=82*1, temperature=1*601, density=600*81

density should be 601*82

Thank you so much, it worked.

You need to transpose the density matrix:

for i=drange(1:100) 
    P=101;
    result1=zeros(100); 
    result1(i)=interp2(Pressure,temperature,density',P,temperature(i));    
    disp(result1(i)) 
end
