tripuls — Generate sampled triangular pulses.
tripuls(T) returns samples of a unit-width triangular pulse centered at zero. tripuls(T, W, S) uses width W and skew S in [-1, 1].
Syntax
Y = tripuls(T)
Y = tripuls(T, W)
Y = tripuls(T, W, S)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
T | NumericArray | Yes | — | Sample times relative to the pulse center. |
W | NumericScalar | No | 1 | Pulse width. |
S | NumericScalar | No | 0 | Skew in [-1, 1]. |
Returns
| Name | Type | Description |
|---|---|---|
Y | NumericArray | Triangular pulse samples. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:tripuls:InvalidInput | Input times cannot be interpreted as real numeric samples. | tripuls: expected real numeric input |
RunMat:tripuls:WidthInvalid | Width is not a positive finite scalar. | tripuls: width must be a positive finite scalar |
RunMat:tripuls:SkewInvalid | Skew is not a finite scalar in [-1, 1]. | tripuls: skew must be a finite scalar in [-1, 1] |
RunMat:tripuls:ArgCount | Too many input arguments are provided. | tripuls: expected 1, 2, or 3 arguments |
RunMat:tripuls:InternalError | Internal tensor construction or GPU gather fails. | tripuls: internal error |
How tripuls works
- Operates element-wise on real numeric scalars, vectors, matrices, and N-D tensors; preserves input shape.
- The pulse is zero outside
[-W/2, W/2]and reaches one atS*W/2. - The width must be positive and finite.
- The skew must be finite and in
[-1, 1]. - Complex and text inputs are rejected with a builtin-scoped error.
Examples
Default centered triangle
t = -0.5:0.25:0.5;
y = tripuls(t)Expected output:
y = [0 0.5 1 0.5 0]Skewed triangle
t = -1:1;
y = tripuls(t, 2, 1)Expected output:
y = [0 0.5 1]Using tripuls with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how tripuls changes the result.
Run a small tripuls example, explain the result, then change one input and compare the output.
FAQ
Can tripuls be used inside pulstran?⌄
Yes. pulstran(T, D, 'tripuls', W, S) evaluates triangular pulses centered at each delay.
