Hi, and the Notation packag with the Symbolize[] function help not ? Regards Jens "Mukhtar Bekkali" <mbekkali at gmail.com> schrieb im Newsbeitrag news:dsccna$pae$1 at smc.vnet.net... | Hi: | | I want to use local assignment done for a subscripted variable, where | x1 is ought to be read as x subscript 1, and evaluate at local values | function g[x1] and use the result later on.
