Getting started

Plot a sine wave

plot a sine wave.

catalog/demo_sine.qu

The simplest possible version of the thing Qu is built for: a time axis, a waveform, and a plot. No filtering, no noise, no units -- just sin().

What it exercises

• to (range), elementwise sin(), plot(), show plot

How it works

t = 0 to 2 * pi step 0.05
y = sin(t)

plot(t, y)
show plot

Results

The whole program

Runnable as it stands: qu run catalog/demo_sine.qu
