This function recovers the matrices packed in a mksys or tree variable selectively.
Syntax
[b1,b2,,bn] = branch(tr,PATH1,PATH2,,PATHN)
Description
Branch returns N sub-branches of a tree variable tr, if nargin = 1, the root branches are returned in sequence by numerical index; otherwise, the branches returned are determined by the paths PATH1, PATH2,, PATHN. Each path is normally a string of the form
PATH = '/name1/name2//namen';
where name1, name2, et cetera are the string names of the branches that define the path from the tree root to the sub-branch of interest.
Alternatively, you may substitute for any PATH a row vector containing the integer indices of the branches that define the PATH. For example, if
S = tree('a,b,c','foo',[49 50],'bar'), then branch(S,'c') and branch(S,3) both return the value "bar".
Examples
