Hi every one,
I am trying to plot acceleration data, which I always have in X, Y & Z direction.
To avoid doing everything 3 times, I have created a cell array: names = {'X', 'Y', 'Z'}.
I now want to plot this data in 3 subplots using a for loop, which yields something like this:
for i = 1:length(names)
figure();
subplot(3,1,i);
plot(UA_SEG.Acc_(names{i}));
end
In which UA_SEG is a table containing the data I'm using.
However, I am doing something wrong in accessing the cell array, as it won't plot and I get the error "Error using tabular/dotParenReference (line 69), Unrecognized variable name 'Acc_'."
Which means that it does not recognize the first element of the array as being 'X', but I am not sure which braces or indexing to use to make this work.
Thank you in advance
Inti

xyz = 'XYZ';
figure()
for k = 1:3
subplot(3,1,k)
plot(UA_SEG{:,['Acc',xyz(k)]})
end

Thank you Stephen!
I had looked at a lot of information pages before, but I hadn't found that one yet.
