comment How to speed up the calculations of the Gröbner basis of the following system of equations?
Many thanks for pointing my mistake. I have removed x, y and z fro the second argument. As for the second question, yes I have and does not make much difference. Is there a way to indicate that k1 to k9 and a are constants?

comment Import a jpeg file and a mov file and display them side by side
Unfortunately not. Would Import with imageSize do? If so, sizes are: {1280, 960} for the picture and {588, 632} for the movie. Many thanks.

comment Import a jpeg file and a mov file and display them side by side
I can see the image and a box with a black strip on it. No animation though. The movie is there but it has not been resized so that is the reason I can only see a very tiny strip of it.

Unfortunately it did not work with the mov file I have. ListAnimate works separately but not with the static image.

@MarcoB. Many thanks but I am not sure how to set ContentSize within Import. Import takes only 2 parameters.

comment How to deal with Part in a function?
@m_goldberger. Thank you ever so much. Please correct me if I am wrong. My intent of having everything under one function was to use it within Manipulate so that I could vary alpha and the function under fun. Do you think that can be done with the functions above? One last question. Could you so kind to explain (_Function | _Symbol), please?

comment How to deal with Part in a function?
@m_goldberger. Many thanks. Yes, you are right when you say that I don't have sufficient experience of Mathematica's core language. Please believe when I say that I am trying but it hasn't been easy. The code you sent works as needed. Many thanks. Finally, how to put everything under one function ? (Final part of my question).

comment How to speed up a system simulation?
@2012rcampion. The first option worked ok, although I had to use Quiet to suppress the warning messages. As for the second option, I could not figure out how to do it (it does not give the results as in option 1). Could you so kind to tell me how to use option 2, please? Many thanks

It seems ok for a linear system (I shall give it a try). Many thanks.

@Oleksandr. Many thanks. Unfortunately it isn't. Could you be so kind to tell me how I could use Compile with model1? Thanks.

@2012rcampion. Many thanks. I think I can modify the generating function as you have suggested.
