Debugging Programs

Here are some suggestions for debugging Mathematica programs.

• First, try to divide the program so that each command resides in a single cell. That way, you can evaluate each command and see the resulting output.

• If you use an iterative command, like Table, you should try setting the iterative variable instead. For example, the command

  Table[f[x],{x,1,5}]

  becomes

  f[1]
f[2]
f[3]
f[4]
f[5]

• The previous suggestion works well for function definitions using Module or Block.

• You can use the Print command to look at values of variables inside nested commands.
