Hi! Using Petsc 3.4.4, compiled to support complex numbers, I'm getting a completely white figure when plotting a matrix with purely imaginary elements, using MatView(mat, PETSC_VIEWER_DRAW_WORLD). So I cannot see the nonzero structure from the plot.
For real matrices (still using the complex-enabled Petsc), I'm getting red and blue points corresponding to positive and negative elements. Is it possible to get Petsc to show the nonzero elements of a complex matrix, by checking the absolute values of each element? Best regards Torquil Sørensen
