Purpose
Angle measure technique.
Synopsis
- [y,s] = anglemt(yx,options);
Description
INPUTS
- x = a row vector on which angle measurements are made. If (x) is an MxN image layer it is converted to x(:)'.
OUTPUTS
- y = 4x1 cell array:
- y{1} = mean angle at each point in s.
- y{2} = mean absolute difference at each point in s.
- y{3} = matrix of angles estimated at each point in s.
- y{4} = matrix of absolute difference estimated at each point in s.
- s = distance scales considered.
Options
options is a structure is a structure array with the following fields:
- xscale: [{1:length(x) evenly spaced}] the x-scale,
- distscale: [{1 2:2:min([200 max(xscl)/2])}] the distance scales to consider.
- sopt: ['all' | 'random'] if x is < 200 then 'all', else 'random'
- 'all' measures angles from all elements of xscale
- 'random' uses a random number of points
- interpmeth: [{'linear'}] interpolation method [see help on INTERP1 input 'method']
