January 2 2011 5:20:31.929 PM DQED_PRB2 FORTRAN90 version A sample calling program for DQED. The problem is to find values for the four variables x(1), x(2), x(3), x(4), which specify the model function: h(t) = x(1) * exp(x(2)*t) + x(3) * exp(x(4)*t) which mininize the sum of the squares of the error between h(t) and recorded values at five values of t: t = 0.05, 0.1, 0.4, 0.5, and 1.0. h(t) = x(1)*exp(t*x(2)*t) + x(3)*exp(t*x(4)) Output flag from DQED, IGO = 4 Computed X: 1.99948 -0.999801 0.500057 -9.95399 L2 norm of the residual, FNORM = 0.424078E-03 Expected X: 1.99947 -0.999801 0.500057 -9.95399 DQED_PRB2 Normal end of execution.
