Documentation Help Center Documentation. By default, the independent variable is z and the transformation variable is n. If F does not contain z , iztrans uses the function symvar. By default, the inverse transform is in terms of n. By default, the independent and transformation variables are z and n , respectively.

### Description

Metrics details. Applying the z -transform method, we study the Ulam stability of linear difference equations with constant coefficients. To a certain extent, our results can be viewed as an important complement to the existing methods and results. The notion of the Ulam stability was originated from a question on group homomorphisms posed by Ulam [ 24 ] in Afterward, this work was generalized by Rassias [ 19 ] for linear mappings by considering unbounded Cauchy differences.

In mathematics and signal processing , the Z-transform converts a discrete-time signal , which is a sequence of real or complex numbers , into a complex frequency-domain representation. It can be considered as a discrete-time equivalent of the Laplace transform. This similarity is explored in the theory of time-scale calculus. The basic idea now known as the Z-transform was known to Laplace , and it was re-introduced in by W. Hurewicz [1] [2] and others as a way to treat sampled-data control systems used with radar. It gives a tractable way to solve linear, constant-coefficient difference equations. It was later dubbed "the z-transform" by Ragazzini and Zadeh in the sampled-data control group at Columbia University in

An Introduction to Difference Equations pp Cite as. In the last four chapters we used the so-called time domain analysis. In this approach we investigate difference equations as they are, that is, without transforming them into another domain.
