Removing white space when using axis equal

I am plotting a figure that needs to have an aspect ratio of 1:1. I am using axis equal and it is working to an extent. For some reason, my figure is in the middle of the image and there is a lot of white space around it. How do I fix this? I need the whole image to take up space. My current plotting code is below.
figure(1)
contourf(root_indices)
clim([1 5])
colormap parula
axis equal off
print(figure(2), '-djpeg', 'Roots Found at Seed Point Location1.jpg', '-r300')

Perhaps instead of using axis equal you might want to adjust the axes DataAspectRatio https://www.mathworks.com/help/matlab/ref/matlab.graphics.axis.axes-properties.html#budumk7-DataAspectRatio which can also be done using daspect
But see also PlotBoxAspectRatio axes property which can also be adjusted using pbaspect

Ran in:
Call axis tight after axis equal
figure
imagesc(rand(10,50))
axis equal
axis tight

This didn't work. There is still so much white space around the image.

After the plot use your mouse and resize the figure and eventually the axes with interactive tool (the arrow button in the toolbar)
You might use menu File => Generate Code and insert the relevant part in your code.

I'm going to guess that this is relevant:
https://www.mathworks.com/help/matlab/creating_plots/save-figure-with-minimal-white-space.html
Otherwise, if you fix both the figure and axes aspect ratios, then there must necessarily be a bunch of padding if they don't match.
In other words, the first step is to adjust the figure so that it's an appropriate shape.
Beyond that, you'll have to provide an example of what exactly your plots look like and what you expect them to look like, because it's not really all that clear why the data aspect ratio would uniquely create padding problems.
