Anglemt

Purpose

Angle measure technique.

Synopsis

[y,s] = anglemt(yx,options);

Description

NOTE : The function ANGLEMT is obsolete and will be removed in future versions. This function is no longer supported.

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']
