In the assemblage's representation, the contribute of the selected element are signed with red colour. The apex is the element's number, while the subscript indicates term's position in the local matrix of the element. By positioning on the table that represent the matrix or the vector and by selecting with the right button of the mouse, a window appears in which is shown the scheme of the sparse matrix obtained: every empty space correspond to a element equal to zero. General data are shown in the right part of the window.
