Hi all,

I am trting to do this:

Px_a1_val = {(sq_val{1, 1}(:,1)) (jp_val{1, 1}(:,1)) (walk_val{1, 1}(:,1)) (stair_as_val{1, 1}(:,1)) (stair_de_val{1, 1}(:,1))}; 
Px_a1_val = cell2mat(Px_a1_val);

which gives me this:

CELL2MAT does not support cell arrays containing cell arrays or objects.

Can you help please?

matrix of

(sq_val{1, 1}(:,1)) (jp_val{1, 1}(:,1)) (walk_val{1, 1}(:,1)) (stair_as_val{1, 1}(:,1)) (stair_de_val{1, 1}(:,1)
