Symplify symbolic expression instead of outputting very large denominator values

77 views (last 30 days)
Hello,
In this code:
z = 1;
Q = z^2 -1.368*z + 0.368 + 0.368*k*z + 0.264*k
I get the answer as:
Q =
(79*k)/125 - 1/9007199254740992
Is it possible to leave the final equation like this form:
Q = 0.632*k
Thanks.

Use the vpa function:
Q = vpa(Q,4)
Q =
0.632*k

That is not imaginary part, that is due to round-off and representation issues.
Take each of your numbers and wrap them with sym() with 'd' option. Like instead 0.368 code sym(0.368,'d')
