LOGISTIC REGRESSION STARTER CODE

logisticStarter.m

This sample MATLAB code implements gradient descent with line search, and also provides a facility to check your gradients numerically. Your job is to implement the function logisticNLP.m that takes the input data and some weights, and returns:

1. The negative log-posterior of the weights for the data.
2. The gradient of the negative log-posterior with respect to the weights
