Algorithm (Workflow)

This function, axis4math, is designed to set the axis for mathematical functions rather than solid geometries or CPLs. It is part of the SG-Library and was introduced in SolidGeometry 5.0.

Input Parameters

varargin: This allows for variable input arguments. The function expects the first argument to be a zoom factor, which defaults to 0.1 if not provided.

Output

ax: The axis ratio after the function call.

Algorithm Steps

Retrieve the zoom factor using getfuncparams with a default value of 0.1 if not specified.
Set the axis to normal and tight using axis normal and axis tight.
Enable the grid with grid on.
Set the view to a 2D top-down perspective using view(0,90).
Get the current axis limits with ax=axis.
Calculate the zoom adjustments for the x and y dimensions:
- dx = (ax(2) - ax(1)) * zoomf: Calculate the x-axis adjustment based on the zoom factor.
- dy = (ax(4) - ax(3)) * zoomf: Calculate the y-axis adjustment based on the zoom factor.
Adjust the axis limits by adding and subtracting the calculated dx and dy values:
- ax = ax + [-dx +dx -dy +dy]: Modify the axis limits to apply the zoom effect.
Apply the new axis limits using axis(ax).

This function is useful for setting up plots for mathematical functions, ensuring that the axis is appropriately scaled and centered.
