%How do I do a t-test between 2 groups of 3D matrices outputting a single matrix of p values?

%Each location in the matrix needs to be compared with the same location in another matrix.

%I've attached an example below but can't get the correct output. Your help would be much appreciated.

% group 1

A = rand(3,3,3);

B = rand(3,3,3);

C = rand(3,3,3);

% group 2

D = rand(3,3,3);

E = rand(3,3,3);

F = rand(3,3,3);

% mean

g1mean = (A+B+C)/3;

g2mean = (D+E+F)/3;

% ttest between groups with output as one 3 x 3 matrix with p values

I suggest you try using the ttest function on Matlab. Refer the MathWorks documentation on how to use it.
