pulstran — Generate pulse trains from named pulse functions, function handles, or sampled prototype pulses.

pulstran(T, D, FUN, P1, ...) evaluates a pulse function at T - D(k) for each delay and sums the results. D may be a delay vector or an N-by-2 delay/amplitude matrix. pulstran(T, D, P, FS) uses a sampled prototype pulse P with sample rate FS and linear interpolation.

Syntax

pulstran(T, D, FUN, P1, ...)

How pulstran works

• The output shape matches T.
• Character, string, and function-handle pulse names are accepted. Built-in fast paths cover rectpuls, tripuls, and gauspuls; other function handles are invoked through the normal feval path.
• A delay vector uses unit amplitude for every pulse.
• An N-by-2 delay matrix uses column one as delay and column two as amplitude.
• Sampled prototype pulses are linearly interpolated at FS; samples outside the prototype support contribute zero.
• Complex and text-valued numeric inputs are rejected with builtin-scoped errors.

Examples

Generate a rectangular pulse train

t = -1:0.5:1;
d = [-0.5 0.5];
y = pulstran(t, d, 'rectpuls', 0.25)

Expected output:

y = [0 1 0 1 0]

Use delay amplitudes

t = [0 1];
d = [0 2; 1 3];
y = pulstran(t, d, 'rectpuls', 0.25)

Expected output:

y = [2 3]

Use a sampled prototype

t = 0:0.5:2;
d = [0 1];
p = [0 1 0];
y = pulstran(t, d, p, 2)

Expected output:

y = [0 1 0 1 0]

Using pulstran with coding agents

Open a RunMat example with live inputs, then ask the agent to explain how pulstran changes the result.
