|
---|
4 | % This function is used by uvmat to plot fields. It automatically chooses the representation
|
---|
5 | % appropriate to the input field structure:
|
---|
6 | % 2D vector fields are represented by arrows, 2D scalar fields by grey scale images or contour plots, 1D fields are represented by usual plot with (abscissa, ordinate).
|
---|
7 | % The input field structure is first tested by check_field_structure.m,
|
---|
8 | % then split into blocks of related variables by find_field_cells.m.
|
---|
9 | % The dimensionality of each block is obtained by this function
|
---|
10 | % considering the presence of variables with the attribute .Role='coord_x'
|
---|
11 | % and/or coord_y and/or coord_z (case of unstructured coordinates), or
|
---|
12 | % dimension variables (case of matrices).
