I'm trying to build a symbolic vector with variable dimension N, and I would like it to be real...
I managed to build the vector with the desired lenght throug str2sym, but I don't know how to set assumption "real" on its variables.
(I would like to use this vector for a linear system).
A = i;
s1=sprintf(' u%d, ',A);
s2=sprintf(' v%d, ',A);
s3=sprintf(' w%d ',A);
stot2=strcat(stot2, s1, s2, s3);
U1=['[' stot2 ']'];
Thanks for any help!
