The step plot automatically includes a dotted horizontal line indicating the steady-state response. In a MATLAB® figure window, you can right-click on the plot to view other step-response characteristics such as peak response and settling time. For more information about these characteristics, see stepinfo.

Since MATLAB® is a programming language, an endless variety of different signals is possible. Here are some statements that generate a unit impulse, a unit step, a unit ramp, and a unit parabola.

The heaviside function returns 0, 1/2, or 1 depending on the argument value. If the argument is a floating-point number (not a symbolic object), then heaviside returns floating-point results. Evaluate the Heaviside step function for a symbolic input sym(-3). The function heaviside(x) returns 0 for x < 0.

For simulation time greater than or equal to the Step time, the output is the Final value parameter value. The numeric block parameters must be of the same dimensions after scalar expansion. If the Interpret vector parameters as 1-D option is off, the block outputs a signal of the same dimensions and dimensionality as the parameters.

2014年1月6日 · The step size for the time vector is determined based on the system dynamics. Define vector — Specify the times to plot as a vector of monotonically increasing evenly spaced time values. For bode , nyquist , nichols , and sigma plots, you can specify the frequency vector by right-clicking the plot area and selecting Specify frequency .

Starting in R2016b, instead of using the step method to perform the operation defined by the System object, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.

2021年7月19日 · How can i plot a unit step function or a piecewise function in Matlab? ... in signal processing and ...

For discrete-time systems with a specified sample time, the function uses the sample time of sys as the step size. For discrete-time systems with unspecified sample time (Ts = -1), the function interprets tFinal as the number of sampling periods to simulate with a sample time of 1 second.

2013年4月7日 · there is a discrepancy between your definition of "step function" and what a step function is. Usually a step function is f(x) = 1 for x > 0, and zero otherwise. Your definition added a "set-to-zero" for x>1. Your f(t) matches the intuitive definition, not your definition. –

2021年10月23日 · I would like to have a smooth step function with specified rise time, with some control of the output. I try to explain better. It is pretty simple to create a piece-wise linear step function and the correspondent smooth function with controlled slope using a …
