Dear matlab users,
Is it possible to convert iddata to cellstr? i tried following code but it dont works.
cellstr(num2str(data.y(:,1)))]; %
%data.y(:,1) has this form 1×1 cell array {500×1 double}
500×1 char array
' 0.166667'
' 0.25'
' 0.333333'
' 0.416667'
' 0.5'
' 0.583333'
' 0.666667'
' 0.75'
in this format i want vector
Thank you very much

Another approach:
data = iddata(rand(1,10)', (0:9)', 0.1); % Create ‘iddata’ Object
y = data.OutputData; % Get ‘OutputData’ As Double Array
ycs = cellstr(num2str(y)); % Convert To Cell Array Of Strings

Ah, I see. I don't have this toolbox and had never heard of it before. help iddata redirected me to help griddata

Close, but you need to access the contents of the cell array, not the entire cell array itself.
data.y(:,1) = {rand(500,1)};
output = cellstr(num2str(data.y{:,1}));

500x1x0 means your arrays are empty. You don't have any data.

From iddata object "data", you can fetch the data arrays as cells using:
y = pvget(data,'OutputData');
In your latest query, y is a cell array of iddata objects. Thus x1 = y{1} will return one iddata object. Then pvget(x1,'OutputData') will return the value of its "OutputData" property as a cell array.
Note that size of 500x1x0 for an iddata object means that the data has 500 samples, 1 output and no inputs signals. The size() operator is specialized (overridden) for iddata objects.
