Open in MATLAB Online I used to have no issues with this back when I used Matlab 2017b but now I can't get the pole placement function to work. here is what I got: >> syms k1k2 k3 s >> A A = 0 1.0000e+00 0 0 0 1.0000e+00 ...
MATLAB Online에서 열기 It’s likely easier to create the differential equaitons as an anonymous function, then integrate them with one of the numerical ODE soivers. Like this: 테마복사 syms x(t) y(t) t Y Dx=diff(x,t) Dy=d...
We do not know what the ordering is, just that for any given formula, it is consistent. It is a programming mistake to count on a particular root number corresponding to a particular meaning, but you can get away with it for any given MATLAB release (but the next release could potentia...
MATLAB 2011a finds the (extremely complicated) symbolic solution whereas MATLAB 2010b just gave up. Here’s another one syms an1 an2; eq1 = sym('4*cos(an1) + 3*cos(an1+an2) = 6'); eq2 = sym('4*sin(an1) + 3*sin(an1+an2) = 2'); ...

You can use "who" to find out what symbols are accessible in the current workspace, and you can use class() to find out which class the variable is; or you can use isa(varible, 'sym') to test if it is a sym
