Interpolation of data in a given area

I have 4 sets of coordinates (representing a square, I need to interpolate and get a 200x200 matrix.

%set of coordinates:
amax=1.49895;
amin=1.49747; 
bmin=2.62186; 
bmax=2.62471;

Заранее спасибо

amax=1.49895;
amin=1.49747; 
bmin=2.62186; 
bmax=2.62471;
N = 200;

avec = linspace(amin, amax, N);
bvec = linspace(bmin, bmax, N);
[A, B] = meshgrid(avec, bvec);

%now demonstrate
scatter(A(:), B(:), '.')
