d2c()

Control Systems

d2c() is a MATLAB®-compatible control systems function for discrete-to-continuous conversion using tustin's bilinear method. converts a discrete-time transfer function (in z) with sample time ts to a continuous-time transfer function (in s). inverse of c2d. Run it online in your browser with SimLab — free, no install, no license required.

Frequently Asked Questions about d2c()

Is the d2c() function free to use in SimLab?

The browser workspace requires no MATLAB® license or installation. Connected features require network access and may have account, tier, availability, or usage limits. You can open d2c() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.

Do I need to install MATLAB to use d2c()?

No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The d2c() function requires no MATLAB® license or desktop software download.

What does d2c() do?

Discrete-to-continuous conversion using Tustin's bilinear method. Converts a discrete-time transfer function (in z) with sample time Ts to a continuous-time transfer function (in s). Inverse of c2d. It is a MATLAB®-compatible control systems function available in SimLab with the same calling syntax as MATLAB® — typically: d2c(sysD, Ts).

Can I run d2c() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls d2c(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
