pyFDN.plot_matrix_grid#

pyFDN.plot_matrix_grid(matrices, *, titles=None, ncols=2, zmin=None, zmax=None, show_ticks=False, title=None, height=None, width=None)[source]#

Plot several matrices as a grid of Plotly heatmaps sharing one color scale.

Each matrix is rendered like plot_matrix() (RdBu, zero-centered, top-left origin, square cells). Use this to compare several matrices side by side, e.g. a feedback matrix against its nearest orthogonal approximations.

Parameters:

  • matrices (Sequence[ArrayLike]) – 2-D matrices to visualise, filled row by row across the grid.

  • titles (Sequence[str] | None) – One subplot title per matrix (supports HTML/<br> for line breaks).

  • ncols (int) – Number of columns in the grid. Default 2.

  • zmin (float | None) – Shared color limits. If both None, uses (-1, 1).

  • zmax (float | None) – Shared color limits. If both None, uses (-1, 1).

  • show_ticks (bool) – If True, label axes with integer row/column indices. Default False.

  • title (str | None) – Overall figure title.

  • height (int | None) – Figure size in pixels. Defaults scale with the grid shape.

  • width (int | None) – Figure size in pixels. Defaults scale with the grid shape.

Returns:

Call .show() to display.

Return type:

Any
