Matrix operator object based on a function handel. MF = MatFun(sz,fun,funt,isvec) Create a operator of size sz based on the linear function fun and its adjoint funt. For a matrix X of approriate size: MF*X is fun(X) and MF'*X is funt(X) If isvec is 0 (default), then the function must be applied on the columns of X individually, otherwise fun and funt are assumed to be "vectorized".
