I use the following code,but very slow.
Map[QuantityMagnitude@
ReleaseHold@WolframAlpha[#, {{"Input", 1}, "Input"}] &, data, {2}]
How to convert it to a matrix that only contains number?
QuantityMagnitude[Map[Interpreter["Quantity"], matrix, {2}]]
still too slow for your needs? $\endgroup$Interpreter["Units"]
, but found nothing. $\endgroup$
