% PR705config - Update the PR-705 configuration.
%
% Syntax:
% config_str (string) = PR705config
% errcode (scalar) = PR705config('Option1', value1, 'Option2', value2, ...)
%
% Description:
% A wrapper for setting various options on the PR-705 using the 'S'
% command. With no input arguments, the function merely returns the device's
% current configuration string. In the multiple input arguments case, here
% are the case-insensitive options and the values they take:
% Lens ID Number of PRIMARY accessory
% Add1 ID Number of 1st ADD ON accessory
% Add2 ID Number of 2nd ADD ON accessory
% Aperture ID Number of Aperture
% Units 0 for English
% 1 for Metric
% ExposureTime 0 - Adaptive
% 25 ... 60000 ms
% CaptureMode 0 - Single Capture
% 1 - Continuous Capture
% Cycles 1 .. 99 - Number of Captures to average
% CalcMode 0 - Power
% 1 - Energy
% TriggerMode 0 - Manual
% 1 - External
% ViewShutter 0 - Open During Measurement
% 1 - Closed During Measurement
% CIEObserver 0 - 2 Degree
% 1 - 10 Degree
%
% Example:
% errcode = PR705config('Lens', 0, 'Units', 1, 'Cycles', 2, 'ViewShutter', 1);
%
