Only the final iteration in the loop is saved. How to save all the iterations ? * Note: all are displayed, but not saved except the last *

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.

Thank you for the reply. I am not clear on how to assign angles to a different element of Angles each loop. Vairble Angles is calling a function. Can you please give an exmaple?

[Cris LaPierre]

Sure.

A(1,i) = X;

This code assigns the value of X calculated in the ith loop to the ith column of A. When the loop ends, A is a vector containing the value of X calculated in every loop.

Cheers. I am making strides but now it's 6x100 rather than 100x6.. Hahahaha. Please look at the attached photo. Do you have any suggestions?

[Cris LaPierre]

You tell it whether to place the data from each loop in a column or a row. Think about your indexing.

You would likely find Ch 5 of MATLAB Onramp quite helpful.

[Konard Adams]

You are appreciated. I got it, much thanks.

I have also noticed by not overwriting each step, it loops faster as well.

cheers!
