2017-11-15 17:44:57 +0200 | commented answer | Calculation Kernel of a matrix Wow, that's a great help for me, really thank you. However, do you have an idea(algorithm) that helps to calculate the left kernel form? as shown on my code, If write like this, it gives, |
2017-11-15 15:38:29 +0200 | asked a question | Calculation Kernel of a matrix I'm trying to write a program in which one part is related to calculation of kernel of a matrix. Its output and expected output are different. For example, A is the matrix whose kernel is wanted. When I calculate its kernel with some programs they give output different, my program is as well. But, when I try to calculate its kernel some others, like SAGE, give output, The above one is what I expect as output. What is the point that I may overlook? Here is my procedure to calculate the kernel in my program, But in that way, I get different then expected one, but SAGE gives the above matrix that actually I expect. I'm really but really confused because both matrix seem right! How come? Sage's output proof, https://i.stack.imgur.com/F3ryq.png My program's output proof, https://i.stack.imgur.com/7Mw8y.png |

2017-10-17 17:59:54 +0200 | asked a question | using sage library in C or C++? Is there a way to run sage library in C/C++ or include the sage in C/C++? For example, I want to calculate minkowski sum, difference or decomposition in C or C++? |
