===Broadcasting===

Borrowed from [http://stackoverflow.com/q/26948776/3565696 other languages], [http://www.octave.org/doc/interpreter/Broadcasting.html octave broadcasting] allows easy and readable vectorization.

<syntaxhighlight lang="Octave">
f = (1:0.1:2);
# put angular frequencies on the first dimension to prepare broadcasting
omega = 2 * pi * f(:);
# time is already on the second dimension (row vector)
t = 0:0.02:2;
# the resulting s will be a 2-dimensional array
s = sin(omega .* t);
# which can be displayed as
pcolor(t, f, s)
xlabel("t (s)")
ylabel("f (Hz)")
</syntaxhighlight>

Note: [https://www.mathworks.com/help/matlab/matlab_prog/compatible-array-sizes-for-basic-operations.html Automatic expansion of dimensions] was added to MATLAB R2016b.
