Multiply a scalar to all column of a table

I've a table, T. I want to mulitply a scalar to all values in the table (similary to scalar multiplication of a matrix e.g. 2*rand(5,5)).

I tried 10*T, it doesn't work.

Any suggestions?

Suppose T is your table variable with it's variable name Var1

T.Var1 = 10*T.Var1;

Sorry if I wasn't clear, but I want to do it for all columns at once.

[Bhaskar R]

var_names = T.Properties.VariableNames     % get the varible names
T = varfun(@(x)x*10,T)    % apply variable*scaler function
T.Properties.VariableNames = var_name    % re assign variable names due to modified names after varfun applying

I believe can also use T{:, :} = T{:, :} .* 10

[Steven Lord]

If all the variables in your table can be concatenated together:

T.Variables = 10*T.Variables;

If they can't, you can use varfun with the 'InputVariables' parameter set to something like @isnumeric to operate only on the variables that are numeric (and so for which it makes sense to multiply by a number.)
