Simple pattern search code base on Hooke Jeeves algorithm

Two files are provided here, PS_global.m is main program and fcn_test.m contains the calling objective test functions. Need to change number of variable NVar in main PS_global.m file base on selection(uncomment) of test function in file fcn_test.m. Program is tested for four variables successfully. For Maximization add -1 sign before the objective function.
