Hi Giulia
global tabla
tabla = app.UITable.Data;
h = cell2mat(tabla(:,1));
tP = cell2mat(tabla(:,2));
tT = cell2mat(tabla(:,3));
if any(tabla < 0)
f = warndlg('Tanto las alturas (cm) como los tiempos (s) deben ser mayores a 0');
end
if strcmp(app.Knob.Value, 'Q vs t (parciales)')
plot(app.UIAxes, h, tP);
end
I replaced the switch statement with an if statement that checks if the 'Knob' variable equals a specific value. I also used the 'any' function to check if any element of 'tabla' is less than zero in the second switch statement.
