rectpuls — Generate sampled rectangular pulses.
rectpuls(T) returns samples of a unit-width rectangular pulse centered at zero. rectpuls(T, W) uses pulse width W.
Syntax
rectpuls(T)How rectpuls works
- Operates element-wise on real numeric scalars, vectors, matrices, and N-D tensors; preserves input shape.
- Returns
1forabs(T) < W/2,0.5atabs(T) == W/2, and0outside the pulse. - The width must be positive and finite.
- Integer and logical inputs are promoted to double precision before evaluation.
- Complex and text inputs are rejected with a builtin-scoped error.
Examples
Default unit-width rectangular pulse
t = -0.5:0.25:0.5;
y = rectpuls(t)Expected output:
y = [0.5 1 1 1 0.5]Custom pulse width
t = -1:0.5:1;
y = rectpuls(t, 0.5)Expected output:
y = [0 0 1 0 0]Using rectpuls with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how rectpuls changes the result.
Run a small rectpuls example, explain the result, then change one input and compare the output.
FAQ
What happens at the exact pulse edge?⌄
RunMat returns 0.5 at abs(T) == W/2, matching the standard sampled rectangular pulse convention.
Can rectpuls be used inside pulstran?⌄
Yes. pulstran(T, D, 'rectpuls', W) evaluates rectangular pulses centered at each delay.
