Create table in AppDesigner
显示 更早的评论
I want to create a table structure that I can use within my program to store and fetch information. However, the code below results in an error of "Unrecognized function or variable 'varTypes" ". Could you direct me on what I am missing? I have a workaround but I would like to understand why the previously defined variables are not seen by the program.
properties (Access = public)
Property % Description
varNames = ["MMSI", "LAT", "LONG", "SOG", "VesselName", "VesselType", "Length", "Width"];
varTypes = ["double", "double", "double", "double", "string", "double", "double", "double"];
ship1 = table('Size',[20 8],'VariableTypes',varTypes,'VariableNames',varNames);
end

You cannot define variables within the properties class section. You can only define your app's properties there. If you want to only use the properties section to define you table then consider the following.
properties (Access = public)
ship1 = table('Size',[20 8], ...
'VariableTypes',["double", "double", "double", "double", "string", "double", "double", "double"], ...
'VariableNames',["MMSI", "LAT", "LONG", "SOG", "VesselName", "VesselType", "Length", "Width"]);
end
Else, you would could define varNames and varTypes as properties and then use those properties to setup your table in the startupFcn.
properties (Access = public)
varNames = ["MMSI", "LAT", "LONG", "SOG", "VesselName", "VesselType", "Length", "Width"];
varTypes = ["double", "double", "double", "double", "string", "double", "double", "double"];
ship1 {table}
end
% Callbacks that handle component events
methods (Access = private)
% Code that executes after component creation
function startupFcn(app)
app.Ship1 = table('Size',[20 8],'VariableTypes',app.varTypes,'VariableNames',app.varNames);
end
end
