Add Operator
ru.snake.spritepacker.writer.expression.AddExpression
weka.filters.unsupervised.attribute.AddExpression
An instance filter that creates a new attribute by applying a mathematical expression to existing attributes. The expression can contain attribute references and numeric constants. Supported operators are :
+, -, *, /, ^, log, abs, cos, exp, sqrt, floor, ceil, rint, tan, sin, (, )
Attributes are specified by prefixing with 'a', eg. a7 is attribute number 7 (starting from 1).
Example expression : a1^2*a5/log(a7*4.0).
Valid options are:
```
 -E <expression> Specify the expression to apply. Eg a1^2*a5/log(a7*4.0). Supported opperators: ,+, -, *, /, ^, log, abs, cos,  exp, sqrt, floor, ceil, rint, tan, sin, (, ) (default: a1^2)
```
```
 -N <name> Specify the name for the new attribute. (default is the expression provided with -E)
```
```
 -D Debug. Names attribute with the postfix parse of the expression.
```
