Problem 42688. Determine the full width at half max
Determine the full width at half max of a curve.
The full width at half maximum (FWHM) is a parameter which is used for describing the width of a peak. https://en.wikipedia.org/wiki/Full_width_at_half_maximum
It is defined as the distance between the two points at which the curve reaches half of its maximum value. For example if y = [0 3 6 3 0], the full width at half of y is 2.
The data in the test-set have only one positive peak. The test suite checks if the solution is correct within an error of 10%. Note that the input array may not necessarily contain an element equal to half of the maximum.

@Carl: the solutions already work this way, in this example the distance between "the points half-way between y(1) and y(2), and between y(5) and y(6)" is 5.5-1.5 (i.e. four, not five)
Ahh, yes. Sorry, my bad
