I would like to use variables with subscripts just like any variable.
There seem to be a couple of problems with evaluation.
Problem 1) I would like to use a subscripted variable as a function
argument, for example:
In[1]= f = Function[{Subscript[t,i]}, Subscript[t,i]^2;
Function::"flpar" :
"Parameter specification {Subscript[t,i]} in
Function[{Subscript[t,i]}, Subscript[t,i]^2] should be a symbol or list
of symbols.
Problem 2) Another problem with evaluation:
In[1]= Subscript[t,i] = 1.0
Out[1]= 1.
In[2]= ?Subscript[t,i];
Information::ssym:
Subscript[t,i] is not a symbol or a string.
How can I make these statements work???? Thanks,
