Plot the Jacobian structure with Gnuplot.

Plot the structure of the Jacobian of a differentiable function with Gnuplot. Nonzero values will be displayed in blue, zeros in white.

When dealing with a dense matrix, the actual values are printed and exact zeros will be displayed in white.

When dealing with a sparse matrix, inserted zeros will also be treated as nonzero values, thus returning the real structure of the sparse Jacobian matrix. In this case, the values returned are 1 for sparse elements, and 0 for actual zeros.

Parameters

f	differentiable function whose Jacobian will be plotted
arg	optimization parameters of the point to plot. This parameter is not relevant when dealing with sparse functions, since it should not change the Jacobian's sparse structure.

Returns

Gnuplot command
