Sampled aperiodic triangle
y = tripuls(T)
y = tripuls(T,w)
y = tripuls(T,w,s)
y = tripuls(T) returns a continuous,
aperiodic, symmetric, unity-height triangular pulse at the times indicated in array
T, centered about
T=0 and with a default width
y = tripuls(T,w) generates a
triangular pulse of width
y = tripuls(T,w,s) generates a
triangular pulse with skew
s ≤ 1. When
s is 0, a
symmetric triangular pulse is generated.
Generate 200 ms of a symmetric triangular pulse with a sample rate of 10 kHz and a width of 40 ms.
fs = 10e3; t = -0.1:1/fs:0.1; w = 40e-3; x = tripuls(t,w);
Generate two variations of the same pulse:
One displaced 45 ms into the past and skewed 45% to the left.
tpast = -45e-3; spast = -0.45; xpast = tripuls(t-tpast,w,spast);
One displaced 60 ms into the future, half as wide, and skewed completely to the right.
tfutr = 60e-3; sfutr = 1; xfutr = tripuls(t-tfutr,w/2,sfutr);
Plot the original pulse and the two copies on the same axes.
