error message adjacent objects

[chirag....@gmail.com]

I am new to Macualay 2, so I apologize if I am asking a very basic
question. I wanted to calculate the Hilbert basis of a cone. I
entered the commands that are in the Macaulay 2 documentation onto my
copy of Macaulay 2 and I get the following error below. I am
wondering if there is another package that I am to install in order
for this to work. I have a Mac, so I followed the standard
installation procedures for the installation of Macaulay 1.4. I also
used the setup() command.


ii1 : C = posHull matrix {{1,2},{2,1}}
/Applications/Macaulay2-1.4/share/Macaulay2/Core/robust.m2:98:26:(1):
[1]: error: no method for adjacent objects:
-- posHull (of class Symbol)
-- SPACE | 1 2 | (of class Matrix)
-- | 2 1 |

Thank you.

posHull comes with the package "Polyhedra". You don't need to install it, it comes with the standard M2 installation. But, as most packages, it is not automatically loaded when you start M2. To load it, just type

loadPackage "Polyhedra"

after starting Macaulay 2.
Then, your line with posHull will work.

See the documentation node

http://www.math.uiuc.edu/Macaulay2/doc/Macaulay2-1.4/share/doc/Macaulay2/Macaulay2Doc/html/_packages.html

for more information on packages.

Thanks! That seems to be exactly my problem.

Did you load the package Polyhedra? (loadPackage "Polyhedra")

I start to use macaulay 2 for solving questions,So I apologize if Iam asking a very basic question. I wanted to calculate the Lyubeznik numbers of
the ring K[x,y,z]/I where / is the ideal (x(y — z),x*y*z). I used walthers algorithm and   I get the following error below.

  

error: no method for adjacent objects:

-- localCohom (of class Symbol)

-- SPACE ideal (x*y - x*z, x*y*z) (of class Ideal)

may I ask you how can solve error I mentioned above.

thank you,

The package Dmodules has a function called localCohom, so perhaps that's the one that

needs to be loaded.

Thank you, I really appreciate you.

Excuse me, I could not load localCohom package in macaulay2. As the matter of fact, recently, I start to use macaulay 2. so may I ask you how can learn to load or writing package or writing Algorithms in macaulay.  How can I  be more familiar with macaulay program .  May i ask you have any  pdf.lecture and educational film? Do you know exist macaulay 2 workshop in August or September. Learning macaulay2 is really vital  for me. I really appreciate you.

Maybe the Macaulay2 book can help you get started. It's available here:

Cheers,

There is no package called localCohom.  But there is a function with that name in the package Dmodules.  So try

loadPackage "Dmodules"

There is no workshop in those months, but this google group is a good way to get questions answered, and there is also the

documentation, which you can read.

I'm really grateful you to answer my questions, I hope that I can promote my knowledge macaulay2 With your guidance in this group.
