Mxest1=(x_T_est1)';
Mxest1(isnan(Mxest1)) = [] %NANs
Myest1=(y_T_est1)';
Myest1(isnan(Myest1)) = [] %NANs
for n=1:length(Mxest1)
mae1=sum(sqrt((x_T-Mxest1(n)).^2+(y_T-Myest1(n)).^2));
end
mae1(1,1)=mae1/n
save('mae1.mat','mae1')
%for new value Mxest1 and Myest1
Mxest1=(x_T_est1)';
Mxest1(isnan(Mxest1)) = [] %NANs
Myest1=(y_T_est1)';
Myest1(isnan(Myest1)) = [] %NANs
for n=1:length(Mxest1)

Hello. I have 51 variegated Mxest1 and Myest1 values. I enter these values manually. As a result, the matrix I want should be mae1=1x51. After manually entering the first value, I save the first result at mae1(1,1). Then I want to save the second value at mae1(1,2). But it doesn't do it correctly. How can I do that? I would be glad if you help.

You have not defined x_T_est1 in your code listing.

Hi,
I understand you would like to store the output from each loop in mae1.
You can achieve this by using a temporary variable “temp” and storing the result inside the “for” loop in “temp” variable. After exiting loop, you can store the value of “temp” variable in “mae1”.
for n=1:length(Mxest1)
temp=sum(sqrt((x_T-Mxest1(n)).^2+(y_T-Myest1(n)).^2));
end
mae1(1,1)=temp/n;
Repeat the same for mea1(1,2).
Hope this helps!
