Can a continuous function be discrete?

For infinite, you may use the equivalent definition of continuity by Heine: "A is limit of f in accumulation point a iff for each sequence an tending to a, the limit f(an) is A", so actually a discrete function can be continuous.

How to convert continuous transfer function to discrete in Matlab?

Description. sysd = c2d( sysc , Ts ) discretizes the continuous-time dynamic system model sysc using zero-order hold on the inputs and a sample time of Ts . sysd = c2d( sysc , Ts , method ) specifies the discretization method. sysd = c2d( sysc , Ts , opts ) specifies additional options for the discretization.

How can a function be discrete?

A discrete function is a function with distinct and separate values. This means that the values of the functions are not connected with each other. For example, a discrete function can equal 1 or 2 but not 1.5.
