Function Documentation

function OK = test_gradient_approx

(

)

performing a test of the gradient_approx routine

It generates a simple 2x2 grid on which the gradients over each edge can be pre-calculated manually (c.f. grad_correct vector), and compares it to the output of gradient_approx()

Return values:

OK	1, if test is OK, 0 otherwise
