Yes, ok, it is already a CAS list. I thought that it was possible to handle a vector or matrix in different mode than with a list...
I was applying your advise to this program.

Quote:2. A CAS program is essentially a function, much like f is a function when declared as f(x):=x^2. When you type f, you will see (x)->(x^2) as this is how the CAS represents functions. Thus, by simply typing the name of a function, you return its actual contents. There is no getting around this.

ok, thank you also for this clear explanation. In the last version of Wronskian it would be the last heavy "error", I can also leave it: the rest works.

Thanks a lot, Han!
