Xstart = 100;
Ystart =   0;
Zstart =  10;
Xend = 200;
Yend =   0;
Zend =  10;
Resolution = 100;
%% Equations
DeltaX = (Xend-Xstart)/Resolution;
DeltaY = (Yend-Ystart)/Resolution;
DeltaZ = (Zend-Zstart)/Resolution;
%% Calling Inverse Kinematics to Loop through each point of the line
for i = 1:Resolution
    
    %% calculating actual point  
    X = Xstart + (DeltaX * i);
    Y = Ystart + (DeltaY * i);
    Z = Zstart + (DeltaZ * i);
    Angles = IKin(X,Y,Z); % Calling inverse function
    disp('Angles :'), disp(Angles)
    writematrix(Angles,'Angles.xls')
    
    %% calculating past points
    A(1,i) = X;
    B(1,i) = Y;
    C(1,i) = Z;
end   
%% Plot
figure 
axis square
plot3(A,B,C,'bp-','lineWidth',1,'MarkerSize',3,'MarkerEdge','g','MarkerFace','y')
grid on; hold on;
plot3(Xstart,Ystart,Zstart,'g.', Xend,Yend,Zend ,'r.','MarkerSize',16)
xlabel('X Axis'); ylabel('Y Axis');zlabel('Z Axis');

You need to use indexing to assign your angles to a different element of Angles each loop. Right now, you overwrite Angles every time. Basically, do the same thing you are already doing with your variables A, B, and C.
