arrowed_line

Function returns data with arrowheads inserted at user-determined frequencies.

This function allows arrowheads to be inserted into a line plot. This allows showing the direction of the line. Input parameters can also change the frequency of the arrowheads and their scale.

Multiple columns of y-axis data can be supplied to and returned by the function to allow plotting multiple arrowed lines in a single figure.

e.g. [x_arrowed, y_arrowed] = arrowed_line(x_orig, y_orig, 1000, 50, 50);
