2019-03-15 02:19:27 -0500 asked a question How to get rid of the Error Message for calling a text file in SageMath I want to input a matrix from a text file and run it in SageMath. The name of the file is Matrix.It is located in the D-drive and it contains a square matrix of order 4. I changed the the name of the file from Matrix.txt to Matrix.sage. I then wrote load('Matrix.sage'); But I got an error message which read Traceback (click to the left of this block for traceback) ... IOError: did not find file 'Matrix.sage' to load or attach Is it possible for Sage-Math to take input a matrix which is stored in a Text File? Can someone kindly comment? Note:I want to input the matrix from the text file and find its determinant in SageMath. 2019-03-14 05:26:56 -0500 asked a question How to input in SageMath from a Output of a C-Program I am using Sagemath. I have the following query: I want to find the determinant of a given matrix A. I know it is possible to input the matrix A as A=matrix([[1,3],[3,4]]) and then calculate its determinant as A.determinant() But I want to calculate determinant of a matrix in the following way: The matrix A is generated by a C-Program.So I have a C-Program which is Matrix.c and its corresponding output file Matrix.exe. I want to use the matrix A generated from the Program in Sagemath and find its determinant. Is it possible to input in Sagemath from a output file of a C Program? I need some help. 2018-08-29 06:40:14 -0500 received badge ● Editor (source) 2018-08-29 06:37:14 -0500 asked a question How to find non-trivial solution of the system in SageMath?? I want to solve a matrix equation in SageMath. I have this matrix $M=$ \begin{bmatrix} 1&1&1&1&1&1&1 1&-1&1&1&1&0&0\ 1&1&-1&1&1&0&0\ 1&1&1&-1&1&0&0\ 1&1&1&1&-1&0&0\ 1&0&0&0&0&-3&1\ 1&0&0&0&0&1&-3\ \end{bmatrix} I have found that det(M)=0 so there exists a non-trivial solution to $MX=0$ I want to solve the equation $MX=0$ but when I solve it in Sagemath I only get the solution $X=0$ How to find non-trivial solution of the system in SageMath?? Please help. 2018-03-18 14:12:08 -0500 received badge ● Student (source) 2018-03-18 14:07:06 -0500 asked a question How to draw figures of Polygons in SageMath I want to draw a picture of a polygon in SageMath which will be unfilled i.e I want to draw figures of triangle,square,pentagon,hexagon and so on and then draw a figure with say 100 sides. I checked the web. I only found plots of 3d figures ,I want 2d figures . Is it possible to draw such a figure in SageMath. Please help me 2018-02-27 10:17:14 -0500 asked a question How to write the given program in sage I am new to sage. I have learned the basics of sage programming from various online notes. I am interested to apply sage in linear algebra and graph theory. My problem is I want to draw a graph as follows: Vertices : Subspaces of a vector space of dimension $n$. Edges: $V_1V_2\iff V_1 \subset V_2$ or $V_2\subset V_1$. Please don't give me the solution. Please help me how to write it step by step or give some resources from where I can find this.
