Hi,
I have a set of variables which I defined in an array and I'm trying
to use "solve" to solve for these variables, but I get the following error:
x = []
N = 3
for i in range(N):
string = 'x' + str(i)
temp_var = var(string)
x.append(temp_var)
Eqn = []
Eqn.append(x[0] + x[1] + x[2])
Eqn.append(x[0] - x[1] + x[2])
solve([Eqn[1]==0], x[1], solution_dict=True)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/mc/.sage/sage_notebook/worksheets/admin/7/code/47.py", line 17,
in <module>
solve([Eqn[_sage_const_1 ]==_sage_const_0 ], x[_sage_const_1 ],
solution_dict=True)
File "", line 1, in <module>
File
"/opt/sage/sage/local/lib/python2.6/site-packages/sage/symbolic/relation.py",
line 509, in solve
sol_dict=[dict([[eq.left(),eq.right()] for eq in solution]) for solution in
sol_list]
TypeError: 'sage.symbolic.expression.Expression' object is not iterable
However the following seems to work:
solve([Eqn[1]==0], x[1])
[x1 == x0 + x2]
The reason I need solution_dict=True is that I need to put the solution
in x[1], which solve does not do. Could someone please help me out?
Thanking you,
Mani chandra
