Ubuntu 10.10
After converting a table (Table1) to a matrix, the matrix has the name "Table12".
I don't know if this is wanted that way, but I was using Origin and Qtiplot before, which name converted matrices e.g. "Matrix1".
I think for a better overview it is better to keep tables and matrices separated in their naming.
The thing is, if you rename your table to something more meaningful (like "sample_xy") you probably want the name of the generated matrix be based on the name of the corresponding table so you can easily see that they belong together. I have to admit that appending a number is not the best choice. Maybe appending something like "_mat" would be appropriate (i.e. "sample_xy" -> "sample_xy_mat" and "Table1" -> "Table1_mat").
Maybe lets go with Knut's suggestion. But low priority.
