I wrote a script to solve the equation ‘*P =Kd .V2 + Kl.VA.BT + C’* . To solve the equation I have used the matrix method. Ie, K*X = P where *[P] = [ P1* * **P2 a column matrix with the total powers P1, P2,P3…….PN at (V1,T1),(V2,T2)……( VN.TN) respectively,\* * P3* * ..* * **PN ]* * * * [K] = [ V12 V1A.BT1 1* * V22 V2A.B T2 1* * V32 V3A.B T3 1* * ………………………..* * VN2 VNA.B TN 1 ]* * * * [X]= [ Kd A column matrix with the unknowns* * **Kl* * **C ]* Now in order to solve multiply both sides with KT, ie *KT.K.X = KTP *or *A.X = B* where *A*=* KT.K *and* B*=* KTP* * * Now we will get the matrix X by using *linalg.solve(A,B*) function which will eventually solve for a set of linear equations of the form Ax=B* * I was able to get the solution. But it is not acceptable since some of the values are negative. SO I want to know is there any way to give some constraints like the solution should contain only positive values and give any range for the solution? I also tried with linalg.lstsq and I am getting the same results * ----- Salahudeen razak* *| +917760902602* *o__* * _> /__ (_) \(_)*... *Burn fat not fuel * * *
