• Numpy has functions for deﬁning matrices. (np.matrix) • In my experience, because arrays operate on matrix rules, it usually doesn’t make a difference whether you use np.array to make a matrix structure or np.matrix. • Other useful linear algebra commands: np.dot, np.cross,

NumPy NumPy provides optimized data structures and basic routines for manipulating multidimensional numerical data. Mostly implemented in compiled C code. Can be compiled with high-speed numeric libraries like Intel’s MKL NumPy underlies many other numeric and algorithm libraries available for Python, such as:

oT solve the problem using CVXOPT, initialize the arrays c, G, h, A, and b and pass them to the appropriate function. CVXOPT uses its own data type for an array or matrix. While similar to the NumPy arra,y it does have a few di erences, especially when it comes to initialization. Below, we initialize CVXOPT matrices for c, G, h, A, and b.
