Question: Matrix in TimeSeriesAnalysis

How can I use a matrix in timeseriesanalysis?

m3 := Import("d:\\bok6.xlsx")

Areachart works fine:

AreaChart([m3], color = "pink" .. "niagara Navy", title = "Tidslinje Tilluft og avtrekk")

But when matrix m3 is entered in timeseriesanalysis it gives a error:

ts1 := TimeSeries([m3], startdate = "2016-08-1", header = "Tilluft VAV setpunkt", enddate = "2016-08-01");

Error, (in TimeSeriesAnalysis:-TimeSeries) invalid input: too many and/or wrong type of arguments passed to TimeSeries:-ModuleCopy; first unused argument is [Array(1..4, 1..1, {(1, 1) = 155.0, (2, 1) = 142.0, (3, 1) = 133.0, (4, 1) = 122.0})]

I have loaded the following packages:

with*matrix  with*linearalgebra  with(plots)  with(Statistics)  with(TimeSeriesAnalysis)
