Double interpolation using lookup tables in matlab

50 views (last 30 days)
hi, i want to create a code that interpolates 2 dimensional data using the method shown in the attached pictures. To clarify, the example in the attachements was calculating the value when angle of attack is 35 degrees and aileron deflection is 2.5 degrees, and we have to interpolate to get the value. I am having a problem converting the formulas into a code that interpolates. Please help.

[x,y]=meshgrid(25:5:50,-10:5:15);
z=[59 76 91 107 122 137;78 98 116 133 149 164;101 127 148 167 184 197;127 155 177 197 214 227;180 212 235 253 266 273;258 289 314 333 346 352];
k=interp2(x,y,z,35,2.5);
