area_under_curve is available in a MATLAB version and an Octave version.
arclength, an Octave code which estimates the arclength of curves of the form (x,f(x)) or (x(t),y(t)).
histogram_display, an Octave code which makes a bar plot of a set of data stored as columns in a file; the first column is the X values, and all the other columns are Y values to be shown as a stack of bars;
lagrange_basis_display, an Octave code which displays the basis functions associated with a given set of nodes used with the Lagrange interpolation scheme.
pwc_plot_1d, an Octave code which converts the definition of a piecewise constant (PWC) function of a 1D argument into plottable data.
