<p>The test of softmax_regression do work after the alternation, but the test case "SoftmaxRegressionFunctionGradient" must add two more lines(at line 131 and 132)</p>

<pre><code>// Get gradients for the current parameters.
arma::mat gradient1, gradient2;
//add these two function calls to evaluate the objective value first, else the probabilites matrix
//would not build
srf1.Evaluate(parameters);
srf2.Evaluate(parameters);
</code></pre>
