hi...how can I convert a structure produced from matlab simulink into another datatype(double for example)such that I can use it into another function?

Functions can take structures (created from Simulink or elsewhere). It depends on which function you're trying to call. That determines what the input should be. A structure is just a collection of data that may contain other types of data. Type the name of the structure into the Command Window to see what's inside. You can grab the data inside by accessing the fields, e.g.

aStruct.thisField

hi...I have managed to get to the field of the structure when I typed:

ahmed.signals where ahmed is the structure name and signals is the field ...signals field contains Values , Dimensions and Label.What I need is to use the Values array (signals data) ...how can I get to Values?

[Jiro Doke]

You're almost there. Just go one more step:

ahmed.signals.values

Hi...I did that , and thankfully I could get to the values but I experienced another problem:the values is n-dimension...what I found is <30000x1x5 double> array, this array is n-dimension ,I need the vector of this array(I mean <30000x1>).... such that I can transpose it , if you have any info...please tell me.Thanks in advance.

Take a look at the command "squeeze".

data = squeeze(ahmed.signals.values);

That will give you 30000x5 double. Now, depending on which column you want, you can type something like data(:, 1)
