Question

Loop Function Issue

As I am trying to solve one problem for my project, I am facing difficulties to solve the loop.

I am looking for Buckling Pressure for different L.b and K value.

Couple things:

  1. A range variable is NOT a vector; it cannot be addressed by an index.  There is an "undocumented feature" that if you follow the definition with an evaluation directly, it becomes a vector.  I DO NOT LIKE OR RECOMMEND THIS.  But I have employed it in the attached file.
  2. the indices in the loop were not correct.  And it didn't need to be vectorized.

Fred already pointed you to the two culprits.

Here is a utility routine to create a vector using the same arguments (first, second last) as used in creating the range and a way to avoid invalid indices in the creation of P.
