Contribute to isnardomatlab development by creating an account on github. The binopdf function expands scalar inputs to constant arrays with the same dimensions as the other inputs. For multidimensional arrays x, nanmin operates along the first nonsingleton dimension. The array class is intended to be a generalpurpose ndimensional array for many kinds of numerical computing, while matrix is intended to facilitate linear algebra computations specifically. Matlab basics pick out parts of a vector consider x a vector of length 7 there are at least 7 elements in the vector, write a script that extracts the 2nd element, a. The multivariate normal, multinormal or gaussian distribution is a generalization of the onedimensional normal distribution to higher dimensions.
