Question

why don't you give me the exact groebner basics?
i have these equations: f1n=121*c1^4 - 5984*c1^3*c3 + 242*c1^2*c2^2 - 43736*c1^2*c2*c3 + 5984*c1^2*c2 - 412446*c1^2*c3^2 + 242*...

Question

can i extract the exact value of c3,c1 and c2?
I have this vector 1x3: [- 2.622e+4094*c3^31 - 1.4849e+4098*c3^30 - 3.4477e+4101*c3^29 - 4.0489e+4104*c3^28 - 2.6497e+4107*c3^2...

Question

how to calculate this equation?
i have: P3=[l1 - (l3y*(2*c3 - 2*c1*c2))/c_delta + (l3z*(2*c2 + 2*c1*c3))/c_delta + (l3x*(c1^2 - c2^2 - c3^3 + 1))/c_delta; ...

Question

can I multiply the denominator to make it disappear?
f1=(- 11*c1^2 + 2043*c1*c3 + 11*c2^2 - 2043*c2 + 11*c3^2)^2 + (497*c2 + (3542*c3)/(c2 - c1*c3) + 11*c1*c2 - 497*c1*c3)^2 - 1; ...

Question

why matlab tells me this?
f2=[o_1z*(l3x-p4x-s_x)*c1^4-2*c2*o_1z*(p4y+s_y)*c1^3+c3*(-l1^2+l4^2-l3x^2-l3y^2-l3z^2-p4x^2-p4y^2-p4z^2-s_x^2-s_y^2-s_z^2+2*l3y*...

I need to create a vector from a symbolic polynomial function,but when i use sym2poly command, matlab tells me it is not a polynomial, how should i do?
thank you. I have the last question. Can i compute groebner basis from f1? (The first function that I put in the first question)...
