[sage-support] Variables that are matrices?

2017-03-06 Thread Martin Martin
Using var('x'), I can create a variable, which can then be used by solve(). However, solve() treats multiplication of such variables as commutative. Is there a way to tell solve() that a variable is a certain type, say a matrix, or more generally an element of a ring? -- You received this

Your question is puzzling since i is a constant, and 1/(s-i) = (s+i)/(s^2+1) so the expressions are equal. John Cremona On 6 Mar 2017 17:35, "Hemanth G" wrote: > Dear All, > > How do you make SageMath to consider the term "i" as a complex term.Here > the SageMath is

[sage-support] Error during Laplace transform of exp(i*x)

2017-03-06 Thread Hemanth G
Dear All, How do you make SageMath to consider the term "i" as a complex term.Here the SageMath is considering "i" as a constant.This question is in wake of problem faced in getting Laplace transform of exp(i*x). The answer should be [s/(s^2+1)] +i* [1/(s^2+1)] whereas I am getting 1/(s-I). The
