MATLAB Online에서 열기 Ran in: Symbolic method - symsy(t) Dy=diff(y); eq=diff(y,2)-Dy-2*t^2+t+5==0; %random conditions %You need conditions to obtain a specific answer cond=[y(0)==0, Dy(0)==1]; z=dsolve(eq,cond) ...
MATLAB Online で開く You cannot do numeric integration if you have an undefined variable. Youcando symbolic integration. Are x and y being passed in? If they are then functionr = F(x, y) symst r = int( H(t,y), t, 0, x); ...
Expression or function to plot, specified as a symbolic expression, symbolic function, vector of symbolic expressions, or vector of symbolic functions. Example: syms t; f(t) = [t^(1/4); t^(2/3); t] [a b]— Interval for polar angle [0 2*pi] (default) | two-element vector | ...
Remember that fplot will be passing in a vector of particular values that it wants to evaluate the function at, but no matter what size of input it passes in, you are always returning the scalar value T, which is a symbolic expression involving the unresolved variableOMEGA. ...

R = subs(S) replaces all occurrences of variables in the symbolic expression S with values obtained from the calling function, or the MATLAB workspace.相当于于用值去替换符号表达式中的变量例如:The statementy = dsolve('Dy = -a*y')producesy =C2/exp(a*t)Then the st...
