[sage-support] Plotting: axes with ticks but with no labels

2011-01-28 Thread Jeff
I would like to be able to plot a function, e.g. plot(sin), that has axes and ticks on the axes but that does not have labels for the ticks. I understand that I might be able to do this using a ticker formatter, perhaps also, by directly using matplotlib, but I do not know exactly how to go about

[sage-support] Ideal and Groebner Basis

2011-01-28 Thread Santanu Sarkar
Suppose in an array A[100], I have 100 polynomials over R.x,y,z=QQ[] I first want to construct an ideal generated by this polynomial. Then I want to find the Groebner Basis. How this can be done in Sage? When we have three polynomials f1,f2,f3 we use the following. I=(f1,f2,f3)*R

I first tried make again, without reinstalling anything. It seemed to complete and sage works properly as far as I can tell.If make finishes without a final error message, can I conclude that the build is ok? I next installed the new atlas spkg and did make again. No error messages. Keith

Of course, with 100 polynomials, any computer algebra system might cry uncle when trying to compute the Groebner basis... depends on the system. regards john perry On Jan 28, 8:34 am, Simon King simon.k...@uni-jena.de wrote: Hi, On 28 Jan., 15:19, Santanu Sarkar sarkar.santanu@gmail.com
