Equations into Tuples

Conor Nelson

Posted 10 years ago

Given a list of equations, I need a function that solves the equations to generate tuples. Examples: eq={x1=0,x2=0,x3=0} Will generate the point {0,0,0}. Similarly: {2 x3 == x2, 2 x1 + x2 == 4, x2 + 2 x3 == 4} Will generate the point {1,2,1} Is there such a built in function?

eq2 = {2 x3 == x2, 2 x1 + x2 == 4, x2 + 2 x3 == 4}; {x1, x2, x3} /. Solve[eq2, {x1, x2, x3}] // Flatten

eq1 = {x1 == 0, x2 == 0, x3 == 0}; sol1 = Solve[eq1, {x1, x2, x3}] // Flatten; {x1, x2, x3} /. sol1 eq2 = {2 x3 == x2, 2 x1 + x2 == 4, x2 + 2 x3 == 4}; sol2 = Solve[eq2, {x1, x2, x3}] // Flatten; {x1, x2, x3} /. sol2

eq1 = {x1 == 0, x2 == 0, x3 == 0};
sol1 = Solve[eq1, {x1, x2, x3}] // Flatten;
{x1, x2, x3} /. sol1

eq2 = {2 x3 == x2, 2 x1 + x2 == 4, x2 + 2 x3 == 4};
sol2 = Solve[eq2, {x1, x2, x3}] // Flatten;
{x1, x2, x3} /. sol2
