for i = 1: length(selected_list)
Speicher_Ort =Bracket_seperation(selected_list{i});
row = Speicher_Ort(1);
col = Speicher_Ort(2);
if strcmp(plot_data_type,'X')
plot(percentage * CEU_X(row,col).absolut(2,1:8000),...
percentage * CEU_X(row,col).absolut(1,1:8000),'r');
hold on;
end
end
Actually this code works perfectly before but suddenly I am geeting this error. please let me know, why i am getting this error?

Can you attach the variable CEU_X? Use the paperclip button to attach the file.

CEU_X evidently does not have a field called that. What does this show
whos CEU_X
CEU_X
if you type those into the command window.

What does this show in the command window
fieldnames(CEU_X)
when you type that in the command window or put it into the script before the error?
If absolut is a field, then you can do
percentage * CEU_X(row,col).absolut(2,1:8000)
like you originally did but not
percentage * CEU_X(row,col).*absolut(2,1:8000)
like you did later.
percentage * CEU_X(row,col).absolut(2,1:8000) says you're taking elements 1-8000 of row 2 of the field absolut of the structure CEU_X, where as CEU_X(row,col).*absolut(2,1:8000) says you're going to take a whole cell (not the contents of the cell like you'd get if you had used curley braces) and then multiplying it by absolut (an 8000 element row vector). You can't multiply a cell by anything. You can only multiple contents of cells if they are numbers. See the FAQ for info on when to use braces, brackets, and parentheses:
