What is Pade approximation method?

In mathematics, a Padé approximant is the "best" approximation of a function near a specific point by a rational function of given order. Under this technique, the approximant's power series agrees with the power series of the function it is approximating.

How to use pade in matlab?

[ num , den ] = pade( T , N ) returns the Padé approximation of order N of the time delay T in transfer function form. The output row vectors num and den contain the numerator and denominator coefficients in descending powers of s. num and den are N th-order polynomials.

How do I delay execution in Matlab?

pause( n ) pauses execution for n seconds before continuing.
