This set of routines allows the user to see how different settings of the statistical parameters affect the final analysis, using small one-dimensional optimal interpolation problems. Three different routines are provided, which are explained in the documentation. It is also necessary to include the routines plclose.pro and plopen.pro in your directory, to enable printing of plots.
Illustration of the program output with two observations. Given certain parameter values, the dotted lines show the one-dimensional analysis for each of two observations used singly, while the dashed line shows the effect of using the two observations together.
