So I had an extremely helpful replier in an earlier question given me an equation for an interpolation function (I didn’t know about the floor and ceil function which would’ve answered my question and given me the opportunity to try writting the interpolation function myself, but I’m not going to look a gift horse in the mouth)
function fitness = interFt(Ft, x, j, k, t)
% Find the floor and ceiling for j and k
j_floor = floor(j);
j_ceil = ceil(j);
k_floor = floor(k);
k_ceil = ceil(k);
% Calculate probabilities based on the distance from the actual values
p_j_floor = j_ceil – j;
p_j_ceil = j – j_floor;
p_k_floor = k_ceil – k;
p_k_ceil = k – k_floor;
% Calculate the weighted fitness for each combination
fitness = 0;
fitness = fitness + p_j_floor * p_k_floor * Ft(x, j_floor, k_floor, t);
fitness = fitness + p_j_floor * p_k_ceil * Ft(x, j_floor, k_ceil, t);
fitness = fitness + p_j_ceil * p_k_floor * Ft(x, j_ceil, k_floor, t);
fitness = fitness + p_j_ceil * p_k_ceil * Ft(x, j_ceil, k_ceil, t);
end
They also gave me an example of how to use the function, but they used a function handle and i’m not sure how it’s being used

for tt=19:-1:1
for i=1:15
for j=1:15
for k=1:15
% here is a snipet of my code that I’m using with one of the
% examples of how I’m using the InterFt function; it’s set up
% exactly how the replier showed
state1 = interFt(@(x,j,k,t) Ft(x,j,k,t), xp(i),zp(j),yy(k),tt+1);
end
end
end
end
Why is Ft not included in the @()?
Why is it that when I change the x’s to i’s it messes things up (while also changing the x to an i in the written function)?
I know you’re not supposed to include the entire code, but let me know if that’s needed to see what I mean
