Text exceeds maximum line length for Command Window display

1 view (last 30 days)
Hi every one I have employed "syms" function to calculate the derivation of an explicit equation. Due to that, the function is very complex, the MATLAB cannot show all results of "sysms" function and the "Text exceeds maximum line length for Command Window display" is presented at the end of results The code has been attached. Is there anyone to help me to save all result of "syms" function? Thanks in advance for your kindly response.

Hello Jahetbe,
Wow, that must be the longest equation I have ever seen, not counting one million digits of pi or something similar. Since it's a polynomial in two variables, do you know the largest value of m,n in x1^m * x2^n?

You use a lot of numeric constants, all of which have 6 significant digits. You cannot justify calculating an exact solution to that equation. The absolute most you could justify would be 12 digits but that would be a difficult argument; really you can only justify 6 significant digits of output.
This leads to the solution:
digits(6)
vpa(expand(Dx1))
vpa(expand(Dx2))
The resulting multinomials appear to have total degree 31.
