How to change the defined signature of a metric in Mathematica(xCoba)

[PUSHPARAJ CHAKRAVARTI]

I haev define a metric using xCoba

met= CTensor[{{ },{ },{ },{ }},{-ch,-ch}]

Where ch represents the chart.

Now I want to change the signature of the above metric from pre defined metric signature from {4,0,0}->{3,1,0}

Please let me know how to do this

Hi,

I don't understand what you mean. Can you provide an example of a CTensor metric with actual components, and then the result that you would like to obtain after the change of signature?

Cheers,

Jose.
