Why do I get the error "Undefined function 'fitrm' for input arguments of type 'table' " ?

Hi,

I am running into the following error when running the following code:

condition = ...
    ['H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' 'H' ...
    'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' 'L' ]';

t_rmanova = table(condition,comptable_both_conditions(:,1),...
    comptable_both_conditions(:,2),comptable_both_conditions(:,3),...
    comptable_both_conditions(:,4),comptable_both_conditions(:,5),...
    'VariableNames',{'condition','pre','balls','btw','basket','post'});

Meas = table([1 2 3 4 5]','VariableNames',{'Measurements'});

rm = fitrm(t_rmanova,'pre-post~condition','WithinDesign',Meas);

I get the error:

Undefined function 'fitrm' for input arguments of type 'table'.

Error in Untitled4 (line 14)

rm = fitrm(t_rmanova,'pre-post~condition','WithinDesign',Meas);

I am essentially trying to run a RM ANOVA. Do I need to oinstall a package? Or is there anopther reason Matlab is telling me "undefined" function?

Thanks!

You need the Statistics toolbox, R2014A or newer.
