• Problem printing a graph on a GUI using scilab 6.0.2 for windows

  Hi all, how are you?.I'm making an GUI in scilab to print and update the graph of a second order system with scilab, this GUI has a fram to input the coefficients of the system and a button to calculate and display the system, the problem is that right now the code written in the .sce file is giving me an error or running partially because it says that the function used to print the response of the system is not defined, that function is "Sis_Motor(...)" .The code is the following:// Parámetros globales de ventana global margin_x margin_y; global frame_w frame_h plot_w plot_h; //Inicialización de parámetros de ventana frame_w=300; frame_h=500; //Altura y anchura del marco. plot_w=600; plot_h=frame_h; //Altura y anchura de la impresión. margin_x=15; margin_y=15; //Margen horizontal y vertical para //elementos. defaultfont="arial"; //Fuente por defecto. axes_w=3*margin_x+frame_w+plot_w; //Anchura de los ejes. axes_h=2*margin_y+frame_h; //Altura de los ejes (100 => Altura de la //barra de herramientas). sistem_graf=scf(10); //Crea una ventana con id=10 y la hace la //ventana corriente. //Color de fondo y texto sistem_graf.background=-2; sistem_graf.figure_position=[100 100]; sistem_graf.figure_name=gettext("Comportamiento del motor"); //Cambio de dimensiones de la figura sistem_graf.axes_size=[axes_w axes_h]; //Nuevo menú h2=uimenu("parent",sistem_graf,"label",gettext("Acerca de")); //Agregando submenús al nuevo menú uimenu("parent",h2,"label",gettext("Acerca de"),"callback","Motor_Acerca_De();"); //Creación del marco mi_marco=uicontrol("parent",sistem_graf, "relief","groove", ...
