`x`	a numeric vector which convert from a time series
`y`	a numeric vector which convert from a time series
`nVec`	the time scale of the detrended operation
`sampleNum`	the number of sample
`qVec`	the order of the multifractal
`detrendOrder`	the detrending polynomial order
`thread`	the multithread number
`sampleMethod`	1 means the determined sample number, other values means the nonoverlap method
`lengthRatio`	detremine how long is the largest scale
