Hi Petr-

Currently SCIRun does not support MATLAB style matrix left division. We will discuss this within our group and consider adding the functionality in the future. SCIRun's direct interface with Matlab may be the easiest way to automate this for the time being. However, as you said, that would require transferring data between the programs.

has anyone tried to do matrix division with the EvaluateLinAlgGeneral

According to the documentation, it is programmed to handle matrix addition
and multiplication.
Specifically, I would need to do matrix left division (least squares
solution) with matrices that are neither square nor column vectors, just
have the same number of rows.
Do we have to write our own C code to perform this in SCIRun? I know I can
do it in Matlab, but am trying to avoid transferring data between the two
