MATLAB Community:
Along with saying hello, I wanted to consult the error that occurred in matlab below and install the DYNOPT toolbox. I try to enter the code and it shows me that the dynopt function is not defined.
Next I will detail the code:
proceso.m
function sys = proceso (t, x, flag, u)
switch flag,
caso 0
sys = [x (2);
-x (2) + u;
x (1) ^ 2 + x (2) ^ 2 + 0.005 * u ^ 2];
caso 1
sys = [0 0 2 * x (1);
1 -1 2 * x (2);
0 0 0];
caso 2
sys = [0 1 0.01 * u];
caso 3
sys = [0 0 0];
caso 4
sys = [0; -1; 0];
de otra manera
error ([ 'unsandled flag =' , num2str (flag)]);
fin
objfun.m
function [f, Dft, Dfx, Dfu] = objfun (t, x, u)
f = x (3);
Dft = [];
Dfx = [0; 0; 1];
Dfu = [];
confun.m
function [c, ceq, Dct, Dcx, Dcu, Dceqt, Dceqx, Dcequ] = confun (t, x, u)
c = x (2) -8 * (t-0.5) ^ 2 + 0.5;
ceq = [];
Dct = [- 16 * t + 8];
Dcx = [0; 1; 0];
Dcu = [];
Dceqt = [];
Dceqx = [];
Dcequ = [];
gráfico.m
[time,state,control] = tuxprint(x,4,2,10,1,3,1000);
[tp,cp,ceqp] = tcceqprint(2,x,4,2,10,1,3,'confungrad',1000);
and what I write in the command windows is:
opt = optimset ( 'LargeScale' , 'off' , 'Display' , 'iter' );
opt = optimset (opt, 'GradObj' , 'on' , 'GradConstr' , 'on' );
opt = optimset (opt, 'TolFun' , 1e-5);
opt = optimset (opt, 'TolCon' , 1e-5);
opt = optimset (opt, 'TolX' , 1e-5);
u = [13 4 -0.5 -2 -1.8 0 0.5 2 0 0];
tiempo = 0.1 * unidades (10,1);
[x, fval, exitflag, salida] = dynopt (1,2,4,2, time, 1, u, [], [], 'objfun' , 'confun' , 'process' , opt);
The last line where dynopt exits gives me the following message: Undefined function or variable 'dynopt'.
Thanks and regards,
