timeseries.ldivide
timeseries: ts = ldivide (a, b)
The element-wise left quotient, a .\ b.
ts = ldivide (a, b) returns the element-wise
quotient of b by a, sample by sample. One of them may be
a number: a scalar, or an array the size of one sample.
The rules for two series are given under timeseries.plus,
save that DataInfo.Units is dropped, since a product or
quotient of units is the unit of neither; MATLAB keeps it where both
series have the same.
