syms (Symbolic Math Toolbox)

Short-cut for constructing symbolic objects

Syntax

syms arg1 arg2 ...
syms arg1 arg2 ... real
syms arg1 arg2 ... unreal

Description

syms arg1 arg2 ... is short-hand notation for

arg1 = sym('arg1');
arg2 = sym('arg2'); ...

syms arg1 arg2 ... real is short-hand notation for

arg1 = sym('arg1','real');
arg2 = sym('arg2','real'); ...

syms arg1 arg2 ... unreal is short-hand notation for

arg1 = sym('arg1','unreal');
arg2 = sym('arg2','unreal'); ...

Each input argument must begin with a letter and can contain only alphanumeric characters.

Examples

syms x beta real is equivalent to

x = sym('x','real');
beta = sym('beta','real');

To clear the symbolic objects x and beta of 'real' status, type

```
syms x beta unreal
```

Note clear x will not clear the symbolic object x of its status 'real'. You can achieve this, using the commands syms x unreal or clear mex or clear all. In the latter two cases, the Maple kernel will have to be reloaded in the MATLAB workspace. (This is inefficient and time consuming).
