This function is to know vbmeg version information.
Usage: [major, minor, alpha_beta, revision] = vb_version;
[comparative_result] = vb_version(comparative_operator, ver_str);
[comparative_result] = vb_version(ver_str);
--- Format1
[major, minor, alpha_beta, revision] = vb_version;
example:
vbmeg version : 0.5-0.a.0
major= 0.5, minor = 0, alpha_beta = 'a', revision = 0
--- Format2
[comparative_result] = vb_version(comparative_operator, ver_str);
[IN]
comparative_operator : '==' or '~=' or '<' or '<=' or '>' or '>='
ver_str : version string formatted as below.
'major-minor.alpha_veta.revision'
ex.'0.5-0.a.0'
[OUT]
comparative_result : true or false.
EXAMPLES
If the VBMEG version is '0.5-1.a.0', and the user supplied version is '0.5':
result = vb_version('==', '0.5');
return result == true : major numbers are same.
If the VBMEG version is '0.5-9.a.0', and the user supplied version is '0.5-8':
result = vb_version('>', '0.5-8');
return result == true
If the VBMEG version is '0.4-3.a.0', and the user supplied version is '0.4-2.b.1':
result = vb_version('<', '0.4-2.b.1');
return result == false
--- Format3
[comparative_result] = vb_version(ver_str);
[IN]
ver_str : version string formatted as below.
'major-minor.alpha_veta.revision'
ex.'0.5-0.a.0'
[OUT]
comparative_result : true or false.
This is the same with result = vb_version('==', ver_str);
