[Math] Straight Line Problem Jacobian Verification

[Ole Ersoy]

Hi Guys,

Reviewing the org.apache.commons.math4.fitting.leastsquares.StraightLineProblem 
(f(x) = ax  + b).   For the jacobian we have:

// Partial derivative wrt "a".
jacobian[i][0] = p[0];
// Partial derivative wrt "b".
jacobian[i][1] = 1;

Should it be:

// Partial derivative wrt "a".
jacobian[i][0] = 1;
// Partial derivative wrt "b".
jacobian[i][1] = 0;

Cheers,
Ole
