HOW CAN I GET INTERPOLATED VALUES OF KN AT DIFFERENT ANGLES AT A CERTAIN VALUE OF DISPLACEMENT?
Please don't shout. ( You typed in all capitals).
Regarding your question:
Use the function linterp.
Success!

That wasnt shouting btw :), just to make matter catchy thats it...
if i use linterp, how can i get value in matrix for a specific value of displacement at different angles?
Werner_E shows us before this function. It can interpolate the data.
Here you are:
BTW, writing in all capital IS considered shouting and doing so usually is considered inappropriate and unpolite.
You may also consider using more meaningful file names as opposed to "Untitled" !
Using spline interpolation instead of linear interpolation might give a smoother curve, but of course it also means to invent data which actually isn't known - especially when it comes to extrapolation (e.g. angles above 60°)
I think what you want is interpolation within a 2D Table, based on both the horizontal and vertical axes. I've done this directly with Mathcad Prime's Bicubic2D interpolation function and it has worked pretty well. Check the help.
