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

Can someone help me to figure out why I am out of range for deletion with this? This code was first used with data that had multiple values in the matrix (i.e. "carbclay" was a matrix with 4 values), but now I’m only doing it with one value, so maybe that’s why it’s not working? I have gotten a lot of help with this so I don’t quite understand it fully, forgive my lack of knowledge when it comes to calling things the right name, hope someone can understand what’s wrong:( The goal of the code is to be able to leave off legend entries if any of the data that I want to plot is missing from my table.
carbclay=[rocktypes(1)]; missingdata1=[];
np = 0;
hp = [];
legtxt = {};
i = find(string(TAllData.gen_rock_type)==carbclay);

missingdata1=[missingdata1,i];

I am recieving the following error:
Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct matrices, use brackets instead of parentheses.
This is the line that is causing the error:
Kernel = @x q.*(exp(-jk.*(sqrt(a^2 + (m1 – (x)).^2)))./(4*pi.*((sqrt(a^2 + (m1 – (x)).^2)).^5)))*((1+jk.*(sqrt(a^2 + (m1 – (x)).^2))).*(2*((sqrt(a^2 + (m1 – (x)).^2)).^2)-3.*(a^2))+((k*a.*(sqrt(a^2 + (m1 – (x)).^2))).^2));
The following variables have already been defined prior to this line:
q, jk, m1, k and a. The only variable is x.
I counted the parentheses, checked the multiplication operator, and I am not trying to construct a matrix.
Some background context:
This line is within 2 for loops. When I take off the function handle (@x) and set x = 1, the code runs without any errors. I plan on integrating this Kernel function and pass it to an array. The original equation is q*(exp(-jk*R)/(4*pi*(R^5)))*((1+jk*R)*(2*(R^2)-3*(a^2))+((k*a*R)^2)) but since the variable X is within R, I expanded R at each instance. R = sqrt(a^2 + (m1 – m2)^2)
