## PROBLEMA CON GUIDE EN UNA INTERFAZE GRAFICA!!! AYUDA!!

Publicado por Roberto (11 intervenciones) el 21/05/2014 23:23:54
SALUDOS! TENGO UN PROBLEMA! SI ALGUIEN POR FAVOR ME PUEDE AYUDAR!

NO ME SALE MI SISTEMA, MATLAB NO LEE QUIZAS ALS CONDICIONES INICIALES Y0 PORQUE CORRE EL PROGRAMA PERO NO ME DA RESULTADOS SOLO APARECE NaN Y LAS GRAFICAS VACIAS

SI ALGUIEN POR FAVOR ME PUEDE DECIR DONDE ESTA MI ERROR PORFAVOR!

AQUI MI CODIGO DEL GUIDE

hola! amigo, con este

sistema de Lorenz

[10*(y(2)-y(1)); 28*y(1)-y(2)-y(1)*y(3); y(1)*y(2)-2.66*y(3)]

aqui le mando mi archivo simple de m ahi si corre completo

hola! de nuevo mi amigo! mira ya lo ensamble completo! son tres metodos con la entrada similar, el de Heun, Runge Kutta 4 orden y el de Adam Moulton

solo que desde el modulo principal Ppl no los llama :( los tres ya corren gracias a tu ayuda

solo que tiene otro problema cuando pongo un sistema de n>2 con el de Adam Moulton no me salne las demas graficas!

es mi ultima pregunta por ayuda! porfavor! ya esta completo! solo que no me los llama
