Which APP should I use if I want to draw a workflow with mathematical expressions on Mac?

I want to find a graphic application that can draw basic workflows with mathematical expressions. For example, I want to draw something like the following figure from "Implementation and Optimization of Differentiable Neural Computers" by Carol Hsin.

Solution 1:

Keynote on the mac can do both. It has standard shapes and the ability to draw lines connected to those shapes. It's a simple way to draw a flowchart. If also supports mathematical expression thru latex. There is an option to insert an equation and you can define anything you like by using latex.

Here is a link to help you with Latex. On this link, you can see what the latex command is for most any symbols you can imagine. I use this page to help me find the correct latex command to put in Keynote.

I have included a very simple and crude flowchart I made in about 5 minutes using Keynote. The math equations are bogus as I was just trying to show the capabilities of Latex.

Solution 2:

Omnigraffle can make flow charts very easily. It's very good at linking lines to boxes, so that you can reposition the boxes and retain the linking.
