The function handle F contains symbolic parameters. Get M = odeFunction(M,vars) M = function_handle with value: @(t,in2)reshape([1.0,0.0,0.0,0.0],[2,2]) Get F = odeFunction(F,vars,a,b,r(t)) F = function_handl
And then I will do optimization based on this nolinear object function objun, so I use the matlabFunction to convert symbolic expression 'objfun' to function handle: 테마복사 if true objhandle=matlabFunction(objfun,'vars',{transpose(dB)}); res=fmincon(objhan...

Expression or function to plot, specified as a symbolic expression or function. [xmin xmax]— Plotting interval for x-coordinates [–5 5] (default) | vector of two numbers Plotting interval for x-coordinates, specified as a vector of two numbers. The default range is [-5 5]. However, ...
利用symbolic方法求解方程的根 y=x∗sinx−x=0 >> syms x y = x*sin(x)-x; solve(y, x) ans = 0 pi/2 %或者 >> syms x solve(x*sin(x)-x) ans = 0 pi/2 2. cosx2−sinx2=0 >> syms x y = cos(x)^2-sin(x)^2; solve(y, x) ans = pi/4 ...
sym(strnum)converts the character vector or string specified bystrnumto an accurate symbolic number without approximation. example symexpr= sym(h)creates a symbolic expression or matrixsymexprfrom an anonymous MATLAB function associated with the function handleh. ...
Inline function: f(a,b,c,x) = a * x^2 + b * x + c ans = 6 但MATLAB官方已经申明在后续的版本中inline会被移除,取而代之的是匿名函数(Anonymous Functions)。之所以有必要搞清楚这个新东西,是因为MATLAB提供的很多其它函数的argin只能为function handle,比如integral, fzero, and fminbnd函数。
(九)Symbolic vs. Numeric 二、Numeric root solvers(利用数值求根) (一)Review of Function Handles(@)(回顾函数句柄) 1、A handle is a pointer to a function(句柄是指向函数的指针) 2、Can be used to pass functions to other functions(可用于将函数传递给其他函数) 3、For example,the input of the...
