adding a value to all values in a table
显示 更早的评论
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'.

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

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;
