I currently use the "disp" function to debug my code and review the intermediate steps. Currently, the "disp" functions do not appear in generated code from MATLAB Coder, so I cannot review the intermediate results in the generated code. Are there any workarounds that allow me to print to the system's command line from the C++ generated code?

There is no direct conversion from disp to printf, but there are tools at your disposal for a workaround.
For example, you can use "fprintf" in MATLAB, which is supported for code generation, and the string/char array you want to print. Check out this link to get started on this:

The above link highlights the necessary ingredients to print information on the command window.
