How to read units from a column in a table in Matlab?

I read in a csv into a table and set each column's units with VariableUnits. I would like to be able to read the units for a certain column (say column 3, "Temp"). I would like to know if the temperature was recorded in degrees F or C or K.

I can use table{1,1}.Properties.VariableUnits to display the units for all the columns, but I can't figure out how to look up the units for just one column.

Also if I want to update the units for one column, how can I do that as well?

I figured out that calling the column at the end of the statement is the way to reference the column.

  table{1,1}.Properties.VariableUnits{column_name}

Is the way to get the column information.

Thanks for this! Just what I needed. Did you find this out from reading documentation or trial and error? I haven't seen it written down anywhere that you can do this!

However, I can't seem to get this to work when there are multiple column_names to index at once. For example:

table{1,1}.Properties.VariableUnits{["var1" "var3"]}

The result returned seems to be that of the last indexed variable. In this example the unit of var3

Jason -

T.Properties.VariableUnits{2}

will get you the units for the second column.

T.Properties.VariableUnits{2} = 'NewUnit';

will update the unit name for that column.
