I cannot get to work the GRP record in MAXIMA. In order to select the maximum value for a group of elements from the results of MAXIMA , I need to enter the boundary values of the group element numbers directly into the FLT record. See the script below. What am I doing wrong?
+PROG RESULTS urs:73.1 $GRP 2 does not work!!! FLT ID 1 NAME 'quad_for.nr' RULE '[20001;20020]'$Boundary values have to be introduced FILT NAME 'quad_for.myy' TYPE EX EXTP MAX XLSX NAME #Path WS 'MX max' ROW 1 COL 1 CLNM YES TIME NO CDB NO ELEM NO FILT NO RESU NO LC NO 3001 QUAD TYPE MY STYP ELEM REPR DLST END
