How to save results to a txt or xlsx file
Posted: Tue Nov 27, 2018 4:40 pm
Hello everyone. I have solved a problem and found the fastest route to go from one point to another. However, I don't know how to save my results to later plot it with another software, like Matlab or Excel.
This is my program:
and this is my attempt to save the values, however, it doesn't work at all.
Can someone please tell me how to save my variables?
Thank you very much.
This is my program:
Code: Select all
$set n 10
set j /0*%n%/;
sets
jlast(j)
jnotlast(j);
jlast(j)$(ord(j)=card(j))=yes;
jnotlast(j)=not jlast(j);
scalar
w_x basicwind direction x axis /10/
w_y basic wind direction y axis /0/
n number of intervals /%n%/
variable
time,
u_x(j),
u_y(j),
x(j),
y(j);
positive variable
step;
equation
diffx(j),
diffy(j),
lim_control(j),
obj;
obj.. time =e= n*step;
lim_control[j].. u_x(j)*u_x(j)=e=1-u_y(j)*u_y(j);
diffx[j]$(jnotlast(j)).. x(j+1)-x(j)=e= 0.5*(w_x*y(j+1)*y(j+1)*y(j+1)+u_x(j+1)+w_x*y(j)*y(j)*y(j)+u_x(j));
diffy[j]$(jnotlast(j)).. y(j+1)-y(j)=e= 0.5*(u_y(j+1)+u_y(j));
y.fx('0') = 1;
y.fx('%n%') = 0;
x.fx('0') = 2.25;
x.fx('%n%') = 0;
model brahstron1 /all/;
option
nlp=ipopt;
solve brahstron1 using nlp minimize time;
Code: Select all
file dem /output/; put dem;
put "time = ", time; put /;
loop(j, put x[j]1:n put y[j] 1:n put /;);
Thank you very much.
