  1. Métodos de Graficación en Matlab Lic. Gabriel Arcos

  2. Graficación. Pasos a seguir. x = 0:0.2:12; y1 = bessel(1,x); y2 = bessel(2,x); y3 = bessel(3,x); Preparar los datos Abrir ventana y configurar figure(1) Ejecutar comando gráfico h = plot(x,y1,x,y2,x,y3); Cambiar propiedades del objeto gráfico set(h,'LineWidth',2)

  3. Graficación. Pasos a seguir. Cambiar las propiedades del eje de coordenadas axis([0 12 -0.5 1]) grid on Agregar etiquetas y texto xlabel('Time') ylabel('Amplitude') legend(h,'First','Second','Third') title('Bessel Functions') [y,ix] = min(y1); text(x(ix),y,'First Min \rightarrow',... 'HorizontalAlignment','right') Exportar el gráfico print -depsc -tiff -r200 myplot

  4. Graficación. Pasos a seguir. xlabel('Time') ylabel('Amplitude') legend(h,'First','Second','Third') title('Bessel Functions') [y,ix] = min(y1); text(x(ix),y,'First Min \rightarrow',... 'HorizontalAlignment','right') x = 0:0.2:12; y1 = bessel(1,x); y2 = bessel(2,x); y3 = bessel(3,x); figure(1) h = plot(x,y1,x,y2,x,y3); set(h,'LineWidth',2) axis([0 12 -0.5 1]) grid on

  5. Funciones de una variable Graficar: x = 0:0.05:2*pi; y = sin(x); plot(x,y,’b-’)

  6. Curvas Paramétricas Graficar las curvas: t=-100:.05:100; x=t; y=(2*t)./(1+t.^2); z=(1-t.^2)./(1+t.^2); plot3(x,y,z,'b-')

  7. Funciones de dos variables Graficar: [X,Y] = meshgrid(-3:.125:3); Z = peaks(X,Y); mesh(X,Y,Z)

  8. Funciones de dos variables Graficar: [X,Y] = meshgrid(-3:.125:3); Z = peaks(X,Y); surf(X,Y,Z)

  9. Curvas implícitas Graficar: [x,y] = meshgrid(-1.5:0.1:1.5); v =(x.^4)+(y.^4)+2*(x.^2).*(y.^2)-2*(x.^2)+2*(y.^2)+1; contour(x,y,v,[1 1])

  10. Superficies implícitas Graficar: [x,y,z] = meshgrid(-1.5:0.1:1.5); v =x.^2+y.^2-z; patch(isosurface(x,y,v,[1 1]),… ’FaceColor’,’blue’)

  11. Configuración de la ventana f = figure; f = figure(’Color’,’white’… ’Renderer’,’OpenGL’… ’DoubleBuffer’,’on’); set(f,’Color’,’white’) set(f,’Renderer’,’OpenGL’) set(f,’Renderer’,’painters’) set(f,’Renderer’,’zbuffer’) set(f,’DoubleBuffer’,’on’)

  12. Configuración del eje de coordenadas axis([0 1 0 1]) set(gca,’Color’,’yellow’) axis([0 1 0 1 0 1]) grid on

  13. Propiedades de objetos gráficos Line Patch Surface

  14. Propiedades de objetos gráficos x=0:.05:2*pi; y=sin(x); h=plot(x,y); set(h,’Propiedad’,valor) set(h,'Color','black','LineWidth',3) • Color • LineStyle: [ {-} | -- | : | -. | none ] • LineWidth • Marker: [ + | o | * | . | x | square | diamond | v | ^ | > | < | pentagram | hexagram | {none} ] • MarkerSize • XData • YData • ZData

  15. Propiedades de objetos gráficos SURFACE Y PATCH: • EdgeAlpha • EdgeColor • FaceAlpha • FaceColor • LineStyle: [ {-} | -- | : | -. | none ] • LineWidth • Marker: [ + | o | * | . | x | square | diamond | v | ^ | > | < | pentagram | hexagram | {none} ] • MarkerSize

  16. Propiedades de objetos gráficos set(h,'FaceColor','yellow','EdgeColor','black')

  17. Definir el punto de vista view([1 1 1]) view(30,30)

  18. Agregar iluminación [x,y,z]=meshgrid(-1.5:.1:1.5); v=x.^2+y.^2-z; h=patch(isosurface(x,y,z,v,1),… 'FaceColor','blue','EdgeColor','none'); view([1 1 1]) lighting gouraud light

  19. Exportar el gráfico print –deps2c –r300 myplot Built-in MATLAB Drivers: Formato Postscript: -dps, -dpsc, -dps2, -dpsc2. Formato EPS: -deps, -depsc, -deps2, -depsc2 Otros Formatos: -djpeg<nn>, -dtiff, -dpng
