Maximum value and its position

Hello,

I have an accelerometric signal and I would like to find the maximum value of the column of the acceleration values and also at what time this maximum value happened (first column). How can I do that?

Thank you,

Guglielmo

[maxvalue, maxidx] = max(Data(:,2))
time_of_max = Data(maxidx,1)

Thank you Walter for your reply. I tried but I recevied the warning: "Error using max

Invalid data type. First argument must be numeric or logical".

The "Data" is a Table.

Thank you!

[maxvalue, maxidx] = max(Data{:,2})
time_of_max = Data{maxidx,1}

I transformed the table in an array and it works!

Thank you Walter!
