21 .+ .\ 21 automatic broadcasting for array operations that allows you to use
22 .- .^ 22 operator notation instead of calling bsxfun or expanding arrays (and
23 23 unnecessarily wasting memory) with repmat or similar idioms. For
24 += .*= &= 24 example, to scale the columns of a matrix by the elements of a row
25 -= ./= |= 25 vector, you may now write
26 .+= .\= 26
27 .-= .^= 27 rv .* M

29 This makes the bsxfun function mostly redundant except for 29 In this expression, the number of elements of rv must match the
