Problem Statement

Write two equal-sized numerical arrays 'x' and 'y' to a two-column text file named 'filename'. The first column of the file contains values from an 'x'-array with a given 'xprecision', the second -- values from 'y'-array with 'yprecision'. For example, considering: The file should look like: This task is intended as a subtask for Measure relative performance of sorting algorithms implementations.

Let's start with the solution:

>> x = rand(10,1); y = rand(10,1);
>> writem("mytextfile.txt", [x,y]);

>> x = rand(10,1); y = rand(10,1);
>> s = text( [x,y], "%10.8f" );
>> writem("mytextfile.txt", s);
