VEMap(x,RPM,Pratio,VE)

function ve = VEMap(x,RPM,Pratio,VE)

x(1) = x(1);%*10000;

Xeval = linspace(1000,6000,300)';
Yeval = linspace(0,1,300)';

% Make them into a grid for use in surf
[xx,yy] = meshgrid(Xeval,Yeval);

zz = griddata(RPM,Pratio,VE,xx,yy,'cubic');

ve = interp2(xx,yy,zz,x(1),x(2));

if isnan(ve)
    ve = -1e10;
end
