Can't download from your website

I tried to download the files from your website, but I could not. Maybe you could upload them directly.

Does the fsolve work at, say, Digits = 15? Try using the fulldigits option to fsolve at your higher value of Digits, 90.

The problem remains

Dear Carl,

Thanks for your reply. It doesn't solve even for Digits=15 and also for fulldigits option.

It may interests you, Accidently I removed this instruction

wiht(Student[NumericalAnalysis]);

And, ran the code again, there was no problem remained!

Again thank you for the reply

It sounds like one package may have been redefining commands used by another package, with incompatibilities in the syntax. This is known to happen once in a while.

I have developed the habit of NOT using:

with(SomePackage);
SomeCommand(x);

and instead use either:

SomePackage:-SomeCommand(x);

or, if the former complains and throws an error, instead:

SomePackage[SomeCommand](x);

This way you keep track of which package you have loaded and what each package does.

Also, you can load only specific commands from a given package:

with(SomePackage,x);

The list of commands available for the package is generated by: with(SomePackage) ;

Edit: removed stuff that could have been misinterpreted.
