# Name: Makefile
# Description: Builds ./bin/polytest, to test the polyfit() function.
# Test Environment: Ubuntu 18.04.4 LTS, GNU Make 4.1, gcc version 7.4.0.
# Author: Henry M. Forson, Melbourne, Florida USA
#
# Synopsis:
#	make clean		-- removes old build files from the repo.
#	make			-- builds the ./bin/polytest executable.
#	./bin/polytest	-- runs the executable.
#
# Results:
#   $ make clean
#   rm -f ./obj/*.o *~ core /*~ ./bin/polytest
#   $ make
#   mkdir -p ./obj
#   mkdir -p ./bin

#   $ ./bin/polytest 
#   Test 1 expected (-3.000000 * x) + 5.000000
#   Test 1 produced (-3.000000 * x) + 5.000000
#   Test 1 passed OK.

#   Test 2 expected (-0.142857 * x^2) + 0.485714
#   Test 2 produced (-0.142857 * x^2) + 0.485714
#   Test 2 passed OK.

#   Test 3 expected error = -4
#   Test 3 produced error = -4
#   Test 3 passed OK.

#   Test 4 expected (1.518293 * x) + 0.304878
#   Test 4 produced (1.518293 * x) + 0.304878
