def plot2ddata xlim=None ylim=None figsize=86 xlabel=None ylabel=None title=None cmap=jet cbar_label=None vmin=None vmax=None mask=True Log=True Plots a 2D intensity map us

The function plot2d takes a 2D array of intensities and creates a 2D intensity map using pcolormesh from the matplotlib library.

The function has several optional parameters:

• xlim and ylim specify the x and y limits for the intensity map. If not provided, the function generates x and y coordinates based on the shape of the input array.
• figsize specifies the size of the figure in inches. The default size is (8, 6).
• xlabel and ylabel specify the labels for the x and y axes.
• title specifies the title for the plot.
• cmap specifies the colormap to use. The default colormap is 'jet'.
• cbar_label specifies the label for the colorbar. If not provided, no label is added to the colorbar.
• vmin and vmax specify the minimum and maximum values for the color scale. If not provided, the color scale is determined automatically based on the data.
• mask is a boolean parameter that determines whether to mask zero values in the intensity map. The default value is True.
• Log is a boolean parameter that determines whether to take the logarithm of the intensity values. The default value is True.

The function returns the figure and axes objects created by matplotlib.

Note: The function assumes that the necessary libraries (numpy and matplotlib) have been imported
