lat1=87.5;
lat2=85;
lon1=-180;
lon2=-175;
coordinates of point_1= [lat2,lon2];
coordinates of point_2=[lat1,lon2];
coordinates of point_3=[lat1,lon1];
coordinates of point_4=[lat2,lon1];
value_point_1=268;
value_point_2=260;
value_point_3=259;
value_point_4=266;
evaluated_point_coordinates=[86,-177];
%I need to interpolate 4 grid points value w.r.t. the evaluated_point_coordinates. Which function I need to use for this grid interpolation?

Probably interp2 with linear, but I discussed some of the details in this blog post about the MATLAB Graphics surface primitive. Be sure to check out the comments section for a nice discussion of some of the options in the Image Processing Toobox.
