I have a variable named A which is a 5000×4 cell array containing M×2 matrices. M varies for each element. 5000 is the number of different measurement for 4 profiles. The following shows only two out of 5000 measurements. First row shows measurement#1 and the second row is measurement#2:

[3413x2 double] [3082x2 double] [3186x2 double] [3143x2 double] [3344x2 double] [3044x2 double] [3200x2 double] [3143x2 double]

I am trying to have all the profile for each measurement in one matrix of size N×2, named B. for example, for the first measurement N=3413+3082+318+3143=12824. So, B is vertcat of the first row of A, it means B is constructed by putting each profile under the previous profile. finally B{i} will be all the profiles for ith measurement.

Could you help me with that?

Accepted answer

A1 = A'; B = arrayfun(@(x)cat(1,A1{:,x}),1:size(A1,2),'un',0)

I think this might work:

B = arrayfun(@(idx) [A{idx,:}], 1:size(A,1), 'un', 0);

Ah, try

B = arrayfun(@(idx) vertcat(A{idx,:}), 1:size(A,1), 'un', 0);

You use arrayfun instead of cellfun because cellfun processes each cell individually whereas you want to process groups of cells.
