adding a value to all values in a table

So I have a 19880x1 table and I want to take the original values of the table, add 300 to those values, and create a new table of the new values. I've looked into varfun but I can't find a way to define func to add 300 without matlab yelling at me for this error: Operator '+' is not supported for operands of type 'table'.

[Walter Roberson]

Are all of the variables the same datatype, and in particular the same numeric datatype ?

[Aaron Dubiansky]

yes, it's just a table of numbers from a test, no text at all

[Aaron Dubiansky]

as in sensor data values.

Answer 1

You address the variables in a table with the dot notation --

t.Var1=t.Var1+300;  % store in place
t.Var2=t.Var1+300;  % make new variable in existing table
u.Var1=t.Var1+300;  % make a new table 

Use whatever is your table variable in place of t and what is the variable name in the table for 'Var1' -- that's the default if don't provide any.

T = array2table(table2array(T)+300, 'variablenames', T.Properties.Variablenames);

Or

T{:, :} = T{:, :} + 300;
