In Matlab, studying control theory, I ran into a pzmap and step functions. These map the poles and zeros of a function into a map, while the other applies a step response. How is this done using Scilab?
For plotting the poles and zeros, see plzr() command. For step response, use csim(). See scilab help for exact usage of these commands.
How would I use this to create a unit step function, u(t), as is commonly used in electrical engineering?
