Hello everyone,

i'm wondering if it's possible to select more than one range of elements of a vector with a single line code.

For example, given the vector a=[1,2,3,...,100], i'd like to select the two ranges [1,...,10] and [90,...,100]. I know that matlab allows to select only a continous range, e.g.:

a = 1:1:100;
b = a(1+89:100);

Thank you very much in advance.
