Hello everyone


I have calculated a correlation matrix, and I would like:

-  to replace each number in this matrix by its absolute value,

-  to replace each value below 0.2 by 0.

Do you know any operators able to do that ?

    hello @jean_claude_van - I would download the Converters Extension and use the "Matrix to ExampleSet" operator.  Then you can use normal operators such as Generate Attributes to do whatever you like.
