22 c o Read the data written by the MITgcmUV state estimation setup and
23 c join them to one vector that is subsequently used by the minimi-
24 c zation algorithm "lsopt". Depending on the specified file name
25 c either the control vector or the gradient vector can be read.
26 c
27 c *dfile* should be the radix of the file: ecco_ctrl or ecco_cost
