How to export the correlation matrix results?

Hi funnyhat,

learning German is definitely an option. However, here is some help now: you can export the correlation matrix by generating a report and write the report to an Excel file. Sounds complicated but is not. The process below shows you how to do this.

Due to your request we also found a tiny bug. Unfortunatly you'll need to close RM to open the written report Excel file without a write protection. This bug is fixed in the svn repository version now and the fix will be part of the next RM update.

Thanks!! you are always so helpful.

It seems that this bug also appears in version 6. If I let RM write a report it cannot be opened while running the same process again.
However, this is still a work-around. An operator which can handle matrix elements would be sooo handy

EDIT: Even more weird... I tried it a second time with exactely the same setup and now it works?!? Well, seems that the rootcause was probably something else with my computer. However, I still consider an operator to process matrix elements is still an important feature.

Hi,

 

Seems that this little bug is still in version 7: I have to end the process first before I can access the report file

 

Best regards

Hallo unvergessbar,

 

schön dich im Forum zu haben!

 

we have created a new operator called Matrix to Exampleset which is available in the Converters Extension. This makes your life easier .

Best,

Martin
