Source Code:

• octave_mistake_test.m, calls all the tests.
• octave_mistake_test.sh, runs all the tests.
• octave_mistake_test.txt, the output file.

• octave_mistake_test01.m, we put numbers in an array, except they don't seem to get there!
• octave_mistake_test02.m, we try to create the -1, 2, -1 tridiagonal matrix but...we don't!
• octave_mistake_test03.m, we try to create the array [ cos ( alpha ), sin ( alpha ) ] but...we can't!
• octave_mistake_test04.m, the command "abs x" seems to work...almost.
• octave_mistake_test05.m, variations of the command "B=1./A" can fail.
• octave_mistake_test06.m, v = rand(3) is NOT a 3-vector.
