11 | *GSASIIexprGUI: Expression Handling* |
---|
12 | ------------------------------------- |
---|
13 | |
---|
14 | This module defines a class for defining an expression in terms of values |
---|
15 | in a parameter dictionary via a wx.Dialog. The dialog creates a :class:`GSASII.ExpressionObj` |
---|
16 | which is used to evaluate the expression against a supplied parameter dictionary. |
---|
17 | |
---|
18 | The expression is parsed to find variables used in the expression and then |
---|
19 | the user is asked to assign parameters from the dictionary to each variable. |
---|
20 | |
---|
21 | Default expressions are read from file DefaultExpressions.txt using |
---|
22 | :func:`GSASIIpath.LoadConfigFile`. |

91 | The free parameters can optionally be designated to be refined. |

94 | 'A*np.exp(-B/C)' |
