fid=fopen('pressure_output.txt''w')

I'm trying to have this create a new file with the given name. The return value for fid is -1. How would I go about creating a new file this way?

You forgot the coma

fid=fopen('pressure_output.txt','w');

Ah you hate to post the question only to hear that you missed a coma
