 Here is developed the testing unit for all the lina functions that need numerical testing.
 
 ## Usage
-For each function in the lina library named in the form of 'lina_something()', here is defined a folder named 'something'. In each folder there are many tests, each one identified by a ti.txt file, for i=1,...,n.
+For each function in the lina library named in the form of _lina_something()_, here is defined a folder named _something_. In each folder there are many tests, each one identified by a ti.txt file, for i=1,...,n.
 Each test file is defined as follows: The first matrix/matrices are the inputs of the function (depending on the function, for example: lina_add() has two inputs A,B and one output C=A+B. A and B have to be the first two matrices in the test file), the last matrix/matrices are the output of the function and after there are input scalar values (ordered in the same order of the function under test) of the function represented as a 1x1 matrix.
+
 For example, a scale test file, that is a test for the lina_scale() function is defined as follows:
 
-[1 1 1, 
- 1 1 1,  <-- Input matrix
- 1 1 1]
- 
-[2 2 2,
- 2 2 2,  <-- Output matrix
- 2 2 2]
- 
-[2]      <-- Input scalar value
+[1 1 1,1 1 1,1 1 1]    
+[2 2 2,2 2 2,2 2 2]   
+[2]
 
-By default, launching test will generate all the testing and provide on the stdout the results.
+Where the first matrix is the input, the second the output and the last is the scalar value.

+By default, executing the test file will generate all the testing and provide the results on the stdout.
