operator with GLPK.To: help-glpk@gnu.org <help-glpk@gnu.org>From:
philliprusso <phillipru...@proton.me>So from reading the documentation I
guess that GLPK can read a file in and that there are a number of
formats to be using. So I would like to start using GLPK in the C++
language for Ubuntu 18.0.45 LTS that I am using for the windows
subsystem for linux and visual studio code.
The problem I am trying to solve is using the summation operator. In
latex format it goes like this:
(For a point list P(x,y)_{n}
\sum {k=0}^{n} \alpha_{k}*x^{i}*y^{j}
The summation with the value k and permuting n times over the formula
alpha of k multiplied by x to the i power multiplied by y to the j
power.
This is the formula for a 2D problem for a finite element analysis
coming from the book Analysis of Structures and Material Behaviors for
Kindle. The number of terms is said to formulate to (n+1)(n+2)/2.
Does GLPK handle the summation operator somehow. Can I see some example
of how to implement such a problem with a GLPK file format (any format
that works is great) and or how to calculate this thing. The trouble I
have is that with the inclusion of i and j with the summation operator I
couldn't find a calculator available on the internet that can handle
such a thing and also so far I have been unable to get help from anyone
that knows how to. Thank You! Any type of help would be greatly
appreciated.Sent with Proton Mail secure email.
