V,d,w eiga,b also returns full matrix w whose columns are the corresponding left eigenvectors, so that wa dwb. If either a or b is a scalar, matlab expands the scalar to match the size of the other input.

The size of a must match the size of b, unless one is a scalar. If a is a symbolic matrix, charpoly returns a symbolic vector. If sys is a generalized statespace model genss or an uncertain statespace model uss, pole returns the poles of the current or nominal value of sys. The symbol o represents a zero and the symbol x represents a pole.

If z and p are matrices, then zplane plots the poles and zeros in the columns of z and p in different colors. You can also determine the real and imaginary parts of complex numbers and compute other common values such as phase and angle. The null space of a matrix contains vectors x that satisfy ax 0. This matrix is rank deficient, with one of the singular values being equal to zero. H freqrespsys,w returns the frequency response on the real frequency grid specified by the vector w. Phpnuke is free software released under the gnugpl license. Real component, specified as a scalar, vector, matrix, or multidimensional array.
