diagram()

Visualization

diagram() is a MATLAB®-compatible visualization function for auto-generate a block diagram from control system connections. shows transfer function blocks, summing junctions, branch points, and signal flow arrows. works with series(), feedback(), and sl_parallel() connections. the connection tree is recorded automatically — just build a system and call diagram(). Run it online in your browser with SimLab — free, no install, no license required.

Syntax

diagram(sys)

diagram(feedback(series(G1, G2), H))

Examples — run diagram() in your browser

G = tf([1], [1 2]);
C = tf([10 5], [1 0]);
sys = feedback(series(C, G), tf([1],[1]));
diagram(sys)

▶ Run

G1 = tf([1], [1 2]);
G2 = tf([3], [1 0 4]);
H = tf([1 0], [1 5]);
sys = feedback(series(G1, G2), H);
diagram(sys)

▶ Run

Frequently Asked Questions about diagram()

Is the diagram() 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 diagram() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.

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

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

What does diagram() do?

Auto-generate a block diagram from control system connections. Shows transfer function blocks, summing junctions, branch points, and signal flow arrows. Works with series(), feedback(), and sl_parallel() connections. The connection tree is recorded automatically — just build a system and call diagram(). It is a MATLAB®-compatible visualization function available in SimLab with the same calling syntax as MATLAB® — typically: diagram(sys).

Can I run diagram() in my browser?

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