For loop syntax in example gives me errors?

Very new to matlab, have done c-programming before

Why does a for loop work for me when i use a matrix syntax

if i=1:10
   i
end

1 2 3...

but when I use the syntax in the examples here: http://www.mathworks.com/help/symbolic/mupad_ref/for.html

i.e. for i from 1 to 20 do ...

I get an error message and in the editor it says 'from' is a parse statement Why can't I paste the exact examples on the matlab page and have it work? Are those examples just conceptual or am I not understanding how matlab works its very frustrating because its something so simple...

Use only in the MuPAD Notebook Interface. This functionality does not run in MATLAB

The link is to the help of the symbolic toolbox, which I know little about. However, its syntax of for-loops differ from that in plain Matlab. See http://www.mathworks.se/help/matlab/ref/for.html
