Hi Aina,
There are some issues with your code. I have listed them below:
- The table "t" loaded in "ImportDataButtonPushed" is not accessible in "CalculateButtonPushed" (it's a local variable).
- "app.UITable_2.ColumnName{2}" is a string, not the data itself.
- You need to add a new column to the table, then update the "UITable_2.Data".
- You should use the updated table data for plotting.
You can refer to the following code as a reference to address these issues:
function ImportDataButtonPushed(app, event)
t = readtable("densitydata.xlsx", "Sheet", 1);
t.Properties.VariableNames{1} = 'Depth';
t.Properties.VariableNames{2} = 'LogData';
app.UITable.Data = t;
end
function CalculateButtonPushed(app, event)
d = app.DrillingFluidEditField.Value;
m = app.MatrixDensityEditField.Value;
t = app.UITable.Data; % Get table from UI component
% Calculate porosity
porosity = (m - t.LogData) / (m - d);
t.Porosity = porosity; % Add new column
app.UITable.Data = t; % Update table in UI
% Plot Porosity vs Depth
plot(app.UIAxes, t.Porosity, t.Depth, '-o');
xlabel(app.UIAxes, 'Porosity');
ylabel(app.UIAxes, 'Depth');
set(app.UIAxes, 'YDir', 'reverse'); % For depth plots
end
I hope it helps!
