Enter the following and examine the output: syms x. The simplest way to enter Maple is to make one or more variables into symbolic symbol (s) using the syms command. xi0:Symbol::subScript (Symbol::xi,0): Then, I converted the notebook to a Live Script, and saw the following code. The interface between Matlab and Maple is smooth and it is easy to move in and out of this Symbolic Math Toolbox. First, I created a MuPAD notebook, and used the statement. However, I'm not aware of such a capability in MATLAB using the symbolic toolbox. I have discovered a nice way to name symbolic variables and would like to extend it a bit, but can't find the correct documentation. Now coming to what you wanted to do, it is possible in Mathematica to hold certain expressions unevaluated and massage it to get it in the final output form that you want. With syms, you can create multiple variables in one command. The second command creates a symbolic variable y with the value y. syms x y sym ('y') The first command creates a symbolic variable x in the MATLAB workspace with the value x assigned to the variable x. The definition for the above function is syms f x a b = Create the symbolic variables x and y using syms and sym, respectively. The closest equivalent of this in MATLAB is called an anonymous function. MuPAD notebooks are separate subprograms of MATLAB r that allow for LaTeX- like typesetting using the symbolic toolbox, in addition to the generation of various specialized.
Below is an example of creating some symbolic fractions and. One additional feature of the toolbox are MuPAD notebooks (Fig- ure 6.1). Matlab allows symbolic operations in several areas including: Calculus Linear Algebra Algebraic and Differential Equations Transforms (Fourier, Laplace, etc) The key function in Matlab to create a symbolic representation of data is: sym() or syms if you have multiple symbols to make. But if you substitute 473/100 and solve then the reasons for various constants that show up in the solution become obscured. It is easier to solve general forms when one uses rational values instead of floating point such as -47.3. For e.g., the pure function definition of a derivative w.r.t. Symbolic Math Toolbox and MuPAD: We discussed the Symbolic Math Toolbox at length in Chapter 4. Answers (1) Solve the form ahead of time. With pure functions, the definition is independent of the actual function and if you chuck in any argument, it should evaluate it. Mathematica behaves exactly the same: MATLAB: syms f x When you initialize f to be a symbolic variable, there is no definition associated with f and hence a derivative w.r.t x should return 0 and a derivative w.r.t. This is not an abnormal behaviour, rather the expected one. This doesn't work, because MATLAB evaluates diff(f,x)=diff(f,y)=0 (it doesn't know if it is a function).
