Description The MXM command compares the sources, point by point, sending the greater value of each comparison to the destination. If one of the sources is a single

value, it acts as a threshold and all values greater than the threshold are sent to the destination.

The default is 800 position units when using TRA, TRB, TRC and is truncated if the trace is longer than destination length. If the trace is shorter than the destination length, the last element is replicated to complete the trace.
