Epanet 2.2 toolkit for matlab

Hello, i am doing a simulation with the toolkit of epanet for matlab. The code is the following:

clear all

%pc fisso
run('C:\Users\Alfio Spectre\Documents\MEGA\MEGAsync\5°Anno\Second Semester\materiale\Epanet_Toolkit\start_toolkit');

% Assuming you have already initialized and opened the EPANET network
d = epanet('CASALNUOVO.inp');

% Get the total number of nodes in the network
numNodes = d.getNodeCount;

% Inizializza una cell array per le categorie di domanda per ogni nodo
allNodeDemandCategories = cell(numNodes, 1);

% Inizializza una cell array per le base demands relative ad ogni categoria di domanda per ogni nodo
allNodeBaseDemands = cell(numNodes, 1);

% Loop attraverso ogni nodo e ottieni le categorie di domanda
for i = 1:numNodes
    % Ottieni l'ID del nodo corrente
    nodeID = d.getNodeNameID(i);
    
    % Ottieni l'indice del nodo corrente
    nodeIndex = d.getNodeIndex(nodeID);
    
    % Ottieni il numero di categorie di domanda per il nodo corrente
    numCategories = d.getNodeDemandCategoriesNumber(nodeIndex);
    
    % Inizializza una cell array per le categorie di domanda del nodo corrente
    nodeDemandCategories = cell(1, numCategories);
    
    % Inizializza una cell array per le base demands relative ad ogni categoria di domanda del nodo corrente
    nodeBaseDemands = cell(1, numCategories);
    
    % Check se ci sono categorie di domanda per il nodo corrente
    if numCategories > 0
        % Loop attraverso le categorie di domanda del nodo corrente
        for j = 1:numCategories
            % Ottieni la categoria di domanda corrente
            category = d.getNodeJunctionDemandName(nodeIndex, j);
            
            % Assegna la categoria di domanda alla cell array
            nodeDemandCategories{j} = category;
            
            % Ottieni la base demand relativa alla categoria di domanda corrente
            baseDemand = d.getNodeBaseDemands(nodeIndex, j);
            
            % Assegna la base demand alla cell array
            nodeBaseDemands{j} = baseDemand;
        end
    end
    
    % Assegna le categorie di domanda del nodo corrente alla cell array principale
    allNodeDemandCategories{i} = nodeDemandCategories;
    
    % Assegna le base demands relative ad ogni categoria di domanda del nodo corrente alla cell array principale
    allNodeBaseDemands{i} = nodeBaseDemands;
end


% Close the EPANET network
d.unload;

At least i obtained the vectors allNodeBaseDemands and allNodeDemandCategories but the values inside of them, respectively a numeric value and just a letter value, have been produced as a cell.

For example regarding the vector allNodeBaseDemands i obtain for the first 10 nodes:

1x1 cell

1x1 cell

1x1 cell

1x1 cell

1x1 cell

1x1 cell

1x5 cell

1x1 cell

1x1 cell

1x1 cell

1x2 cell

Considering the last value 1x2 cell, if i open it i obtain:

1x2 cell 1x2 cell

If i open the first cell i obtain:

0.00428099976852536 0.0427980013191700

And those are the values that i would like to see as i instantly open the above vector. Exactly the same is for the other vector.

I've tried to use every single command i could use to convert cell vectors to other types of values, but anything worked. Please help me, im stucked here since 4 days ago...

To run this code you should have Epanet 2.2 installed and my model CASALNUOVO is attached to this post.

The link to install this toolkit is the following:

It is not possible to create a numeric vector that has 1 column in place but 2 columns when needed.

You can do things like

horzcat(allNodeBaseDemands{:})

to get out a numeric row vector, but such a row vector would not have internal divisions to show you where the cells of length 2 were.

Perhaps you want to

celldisp(allNodeBaseDemands)
