At a certain point I needed the maximum, minimum and mean of a list. Instead of calculating them one after the other I created a proc that calculates everything in one go. And also length and sum.
This is the proc:
proc listNumericStats {thisList} { set length [llength ${thisList}] if {${length} == 0} { error "List cannot be empty" } set max [lindex ${thisList} 0] set min ${max} set sum 0. foreach element ${thisList} { set sum [expr {${sum} + ${element}}] if {${element} < ${min}} { set min ${element} } elseif {${element} > ${max}} { set max ${element} } } dict set stats length ${length} dict set stats max ${max} dict set stats mean [expr {${sum} / ${length}}] dict set stats min ${min} dict set stats sum ${sum} return ${stats} }
