c=19;
>> D=[];
>> for k=1:c;
Z=[X(:,1),Y(:,1)];
p=anova1(Z)
D=save(p)
X(:,1)=[];Y(:,1)=[];
end

"save" to store the result of an applied function...in this case i get 19 individual results...(that need to be stored or saved together as a group) "1 individual matrix"== all 19 answers saved together in a new "vertex" or a 1x19 matrix...sorry still learning the jargon

% X and Y are 3x19 matricies
%
% This syntax makes sure that if you end up having more (or less) columns
% in the future, you don't need to change the code
numColumns = size(X, 2);
% Pre-allocate for speed (create a 1 x numColumns vector)
p = zeros(1, numColumns);
% I used length(p) here to signal the intent that the loop is meant for
% modifying the vector p
for k = 1:length(p);
% using the loop variable *k* means that MATLAB will use a different
% column from X and Y to create Z for each loop
Z=[X(:,k),Y(:,k)];
% this will store the resulting value in the k-th position in the vector
% *p*
p(k)=anova1(Z);
end

the anova1() function displays a table and chart, along with the p-value,the manual says that i can turn this display off,but it doesn't say how... can you rewrite the p(k)= anova1(Z)....i've tried p(k)= anova1(Z, ,'off'),...=anova1(Z,'off')...idk what to do...what am i not getting?

c=19;
% D=[];
p = zeros(c,1); % preallocate
for k=1:c;
Z=[X(:,1),Y(:,1)];
p(k)=anova1(Z);
%D=save(p) unecessary
%X(:,1)=[];Y(:,1)=[]; don't change X or Y!
