I need to save ans as boreSegments .

D = 4.0;            
H_boreholes = [75.0, 100.0, 125.0, 150.0, 75.0];
y = 0;
r_b = 0.075;   
nSegments = 12;
B = 7.5;
for i = 1: size(H_boreholes,2)
    H(i) = (H_boreholes(1,i));
    x(i) = (i*B);
    borefield(i,:) = boreholes (H(i) ,D ,r_b ,x(i), y);
end
boreSegments =  boreholesegments(borefield, nSegments);
function boreSegments =  boreholesegments(borefield, nSegments)
for j = 1:size(borefield,1)
    for i = 1:nSegments
        H = borefield(j).H / nSegments;
        D = borefield(j).D + i * borefield(j).H / nSegments ;
        ans = boreholes...                                        % <<<<<<<<<<<<<<
            (H ,D,borefield(j).r_b,borefield(j).x,borefield(j).y) % <<<<<<<<<<<<<<       
    end        
end
end

classdef boreholes
    properties
        H;D;r_b;x;y   
    end  
    methods
        function obj = boreholes (H ,D ,r_b ,x ,y)
            obj.H = H;obj.D = D;obj.r_b = r_b;obj.x = x;obj.y = y;                        
        end
    end
end

How can I solve this?

Don't need to save in the function with that name, just the output variable name chosen for the return value in the function definition line has to be defined. You make the assignment in the code above that calls the function. But, it doesn't matter what the return variable is named in the function; it's just a dummy anyway so doesn't hurt to leave it as is.

boreSegments =  boreholesegments(borefield, nSegments);
...
end
    
function boreSegments =  boreholesegments(borefield, nSegments)
  ...
  boreSegments = boreholes(H ,D,borefield(j).r_b,borefield(j).x,borefield(j).y);

Thanks for replay. Sir i need to save all argument of ans into a vector or array. Like this :

Unfortunately, this line returns only one property:

boreSegments = boreholes(H ,D,borefield(j).r_b,borefield(j).x,borefield(j).y);

I used this:

   ...
        boreSegments(i,1) = boreholes...
            (H ,D,borefield(j).r_b,borefield(j).x,borefield(j).y); % <<<<<<<<<<<<<<
    end
    boreSegments(:,j) = boreSegments;
   ...
