Why does my data have more than 2 dimensions?

21 views (last 30 days)
I used the "Data Logging" tool in Simulink to collect the outputs of a model, but there seems to be a dimensions problem with one of them.
I extracted the values of the different signals using
>>test=logsout.getElement(1).Values.Data;
but when trying to plot it, I get "Error using plot. Data cannot have more than 2 dimensions." While other signals have the format 18001x1 double, this one has the format 1x1x18001 double. When typing the signal name in the command window, the values look like this:
>>test
test(:,:,204) =
4.2991
test(:,:,205) =
4.2156
test(:,:,206) =
4.2530
How can I convert the Signal to a "normal" one (just the values)?

test = test(:,:)'
will convert your 1x1x18001 to 18001x1

There is multiple options to force your 3d data into a vector
Option 1: use dot notation
% gets you a column vector
a(:) = test(1,1,:);
% gets you a row vector
b(:,1) = test(1,1,:);
Option 2: Shape to your likings
c = reshape(test, [numel(test), 1]);

The first Option didn't work: "Conversion to cell from double is not possible."
The second however did work. The solution of "chocolate Warrior" seems simpler though.
