Constructs the matrix: If a single value is passed, the matrix will be cleared with this value (each column in each row will contain this value). If a matrix with more rows and columns is passed, the matrix will be the upper left nxm matrix. If a matrix with less rows and columns is passed, the passed matrix will be stored in the upper left of an identity matrix. It's also allowed to pass vectors and scalars at a time, but the vectors dimension must match the number of columns and align correctly.
