I understand that you are facing issues using "syms" function in MATLAB. The output from "which -all syms" indicate that MATLAB is using "syms" function from Maple Toolbox instead of Symbolic Toolbox. The issue can be resolved by uninstalling Maple and setting the MATLAB Path to Symbolic...
For example, the command f1 = sym('x') refers to the symbolic variable x and assigns it to the MATLAB variable f1. Get clear f1 = sym('x') f1 = x You can then use the variable f1 in the MATLAB workspace for symbolic workflow, such as finding the zeros of a sine function. ...

例如f= matlabFunction(sin(x)^2),之后调用f(pi/4)得到0.5,实现符号到数值的无缝衔接。 涉及反三角函数时,定义域影响结果。比如acos(cos(4pi))默认返回0,而实际上4π超过反余弦函数的主值范围,需要先对角度取模运算。处理这类问题用wrapToPi函数自动将角度归化到[-π,π]区间。 复数域运算需要特别声明。定义...
these names, MATLAB does not create symbolic scalar variables, but keeps the names assigned to the MATLAB functions. If you want to create a symbolic scalar variable with the same name as a MATLAB function inside a function or a script, usesyminstead. For example, usealpha = sym("alpha")...

思路有点混乱，syms x;y=x^2-1;fsolve(y,-2);你算的是x=2,y=（-2）^2-1还是：-2=x^2-1 求x。如果是前者使用subs 如果是后者，直接写到一起 不
