Matlab - Class : how to declare an internal function returning a value

12 Ansichten (letzte 30 Tage)
Hi all, I am trying to declare an internal function (findScenarioNumber) in a class. This function is supposed to output a number. But I have an error in the line "scenarioNumber = findScenarioNumber(splitDataFolder);" where I'm calling the function: Undefined function 'findScenarioNumber' for input arguments of type 'cell'. Searching but cannot find the good syntax to do that. Anyone can help ?
Here is my code :
classdef SignalStructureProperty < handle
properties
signals
end
methods
function obj = createSignalTopLevelStructure(obj,dataFolder)
splitDataFolder = split(dataFolder,'\');
scenarioNumber = findScenarioNumber(splitDataFolder);
obj.signals.metaData.scenarioNumber = scenarioNumber;
end
function scenarioNumber = findScenarioNumber(splitDataFolder)
scenarioNumber = NaN;
if(~isempty(splitDataFolder))
for i=1:length(splitDataFolder)
if(contains(splitDataFolder{i},'SCN'))
scenarioNumber = str2double(extractAfter(splitDataFolder{i},"SCN"));
end
end
end
end
end
end

You must tell MATLAB that findScenarioNumber is a member function of the class you are currently in
scenarioNumber = obj.findScenarioNumber(splitDataFolder)
You must use obj as the first argument
function scenarioNumber = findScenarioNumber(obj,splitDataFolder)

I would make findScenarioNumber a class-related function rather than a method of the class. See this documentation page for an example of this technique.
