Dear friends, I am trying to export a 30*30 matrix (M) with entries function in x and y to a txt file in order to use it by another program. I am using: Export["filename.txt",M]. I have two problems: 1. I want to reduce the precision of the coefficients of x & y. When I use N[M,n] or SetPrecision[M,n], the precision is reduced within the Notebook but not in the exported file. How to reduce the precision in the exported file? 2. Some entries look like "5*x + 3*y", which leaves spaces around the plus or minus signs. Is there a way to tell Mathematica not leave these spaces because the other program assumes that this is a new column? I also tried to write M//InputForm and just copy and past it, but I get a lot of expressions such as 1.935*^-6 which the other software cannot understand. Is there a way to write it in the form: 1.935e-6?
