2017-05-12 01:50:21 +0100 | commented answer | solve with many variables thanks you for your time may be i didnt understand you'r answer so we start with my matrix k which contains many variables im asking if i can compute all eigenvalues of this matrix such that if we suppose that x is an eigenvalue of this matrix i want to find some function f such that x=f(a,b,c,s1,..s6) and i need that this function must be sumbolic exxample let A=matrix([[a,0];[0 b]]) f(a,b)=A.charpoly()=(a-x)*(b-x) f(a,b)=0 thats mean x=a or x=b what is a simple example but with my metrics I can't get some results in this forme |

2017-05-11 12:04:33 +0100 | asked a question | solve with many variables hi please i have a problem i have a MATRIX contains many variables, and i want to find the eigenvalues of this matrix in function of this variables i let you my matrix here and my code but i can get the solution but if i give to the variable c=0 or b=0 i get the solution so please can you help me |
