Open in MATLAB Online d = solve('x=(2^x)*b+c'); n = subs(d,{'b','c'},{2,3})% Put 2 for b, 3 for c If you are doing the substitutions in a loop, this will probably be faster: C = matlabFunction(d);% Convert symb
MATLAB Online에서 열기 I have used the follwing modification with my code using PDE toolbox. When I click f5, the MATLAB shows busy for a long time without providing any solution. What sort of change should I bring now? functionsolve_and_pl...
another numeric solver without Symbolic Math Toolbox, you can convert symbolic expressions to MATLAB® functions by usingmatlabFunction. This conversion allows you to use the resulting function with other solvers in different MATLAB products, such asfsolve(Optimization Toolbox)in Optimization Toolbox...
seeSelect Numeric or Symbolic Solver. An equation or a system of equations can have multiple solutions. To find these solutions numerically, use the functionvpasolve. For polynomial equations,vpasolvereturns all solutions. For nonpolynomial equations,vpasolvereturns ...
This MATLAB function numerically solves the equation eqn for the variable var using variable-precision arithmetic and returns the solutions with 32 significant digits by default.
