Standard Subscripting

Provides the capability of selecting ranges and strides in addition to the ability to select data using a vector of integer indexes. Standard subscripting indexes must be an integer. A range subscript selection accepts a beginning and ending index separated by a colon :.

    T(0:20,0:)

    Another option is to leave out the start, 
    end or both:

    T(:20,:180) or T(0,:)

    An index can be reversed using a negative stride:

    T(::-1,::-1)

    An index can be subsampled using a positive stride:

    T(::2,::2)
