Hello Everyone.

From :

"This array index is invalid for this array." ?. How to make a correction ?

    Thanks in advance.

I don't recognize the function "zeros".

Try this:

Neither do I. (see "x.cos(x) - sin(x) = 0 solve , x ?" 's post).

This "zeros" is not a built-in Mathcad function; it's probably a user defined function in the sheet you're referencing.  (Many long-time users have hidden regions of utility functions at the top of their template sheets.)

The sequence I showed (defining only the last element) will create an array or matrix full of zeros of that size and does not require a utility function.

I'm very sorry, Fred.  I made wrong typing in the program function.
