T = [0.8 -0.7]
E=2e4*[1; 1; 1];
A=1*[1; 1; 1];
temp_coef = [0 0 0 ];
change_temp = [0; 0; 0 ];
fab_error = [0; 0; 0 ];
F0 = -T * (A(nodei)*E(nodei)*((temp_coef(nodei) * change_temp(nodei)) + ( fab_error(idof) / L )))
nodei is computed elsewhere and selects the correct value from the matrix, the code is part of a loop where nodei will go from 1 to 3, thanks in advance, please ask if i have said enough information and i will try to get back or post if i find the answer else where thank you
hi everyone... could anyone try and explain to me how this isn't working??.. im lost at it .. thanks in advance kyle
