Question 1788: Hi,
Is there a software to write a linear system of equations (it's actually an optimization problem), and solve it. it's of this kind
minF= Y.Y + w(X.X)+ s(Z.Z) with
Y= a + bI + cD + dI* + eD*
X= f + gI + hD + iI* + jD*
Z= k + lI + mD + nI* + oD*
All lower case are parameters, and adctually they have indices (is there something to write that easily, it's a pain under Word...)
I need to diiferentiate F with respects to I and D, then write I and D as functions of I* and D*.
I can do it myself but it takes a really long time and even longer to type it, is there a solver for that??
thanks so much for your help Answer by longjonsilver(2297) (Show Source):
You can put this solution on YOUR website! yes there will be software for this....the whole point of linear algebra is to generate good structured equations that software can churn through.
As to what is available...i do not know. Look on google for "linear algebra free software" etc and see what is available.
