2019-04-17 10:21:22 +0200 | answered a question | General solution for a matrix Ok i also had this equation for p and i replace x in that equation and that it is how i got the answer that i wanted I think that sagemath wants to use matrices with multiplication not as a place that you can throw a function |

2019-04-17 09:03:35 +0200 | commented answer | General solution for a matrix Thank you but i did make a wrong use of the word solution I want to replace the x1 and x2 with numbers and use that result on something else So on the example before i want to get the result of [14, 6] |

2019-04-17 08:18:34 +0200 | asked a question | General solution for a matrix I have a matrix named When I try to solve the matrix with this line: I get this error: In general i want to use something like this, the arguments are x1 and x2 and the x is a list of numbers that it will change on every loop But it reproduce the same error |

2019-04-17 08:18:34 +0200 | asked a question | General solutions for a matrix I have a matrix named p and with the values
[-10 when i try to solve the matrix with this line: "print(p(p.arguments()[0] == 0, p.arguments()[1] == 0))" i get this error: ValueError: use named arguments, like EXPR(x=..., y=...) I want to provide a general solutions any ideas ? |
