MTGEN,[<itim>],[<ninc>],<n1>,<n2>,[<inc>],[<mx>],[<my>],[<mz>]

generates <itim> (default: 1) sets of translational masses in the nodes specified by the numbers obtained by incrementing with <ninc> (default value: <n2>-<n1>+1) the node numbers belonging to the node pattern defined by <n1> to <n2> with step <inc> (default: 1); while at the same time incrementing the pattern masses with <mx>, <my>, and <mz> (default: 0). This instruction works similarly to the NGEN command, with the difference that translational masses and not coordinates are generated.
