E.g., the projection of Polyhedron(vertices=[(-1,-1), (1,3), (5,-2)]) onto the line $y=x$.Max AlekseyevThu, 03 Oct 2019 02:08:37 +0200https://ask.sagemath.org/question/48155/dimensions of imagehttps://ask.sagemath.org/question/45765/dimensions-of-image/ I am having a little trouble when trying to specify the dimensions of a poset which I wish to see the graph of. I use name.show(figsize=[x,y]) but it's not giving me the expected image since it's only conserving the ratio, so it leaves off the y variable. If I wish to see the graph of the poset with dimensions 8x10, it should let me do so with the option figsize=[8,10], but it does not.
Can anyone help me with this issue?
Thank you in advance.StivenTue, 12 Mar 2019 02:10:26 +0100https://ask.sagemath.org/question/45765/Change dimensions of graphhttps://ask.sagemath.org/question/45761/change-dimensions-of-graph/ I am having trouble when trying to define the dimensions of a graph. I wish to have the graph of a poset with dimesions 8x10 (8in length and 10in width) but I don't know how. I tried figsize=[8,10] but it did not work since all it does is conserve the ratio.
Any given help is much appreciated. Thank you.StivenMon, 11 Mar 2019 19:46:42 +0100https://ask.sagemath.org/question/45761/vdim(std(I)) and vdim(I) returning different answers - Singularhttps://ask.sagemath.org/question/39756/vdimstdi-and-vdimi-returning-different-answers-singular/I thought std just put the ideal in a nicer format, so the answer should be independent. In this case I have 2 larger equation f_1, f_2 and I = jacob((f_1, f_2)). So it ends up being around 18 equations.
I get vdim(std(I)) is the expected answer while vdim(I) the answer is a bit to big.
Any help would be appreciated.
