One command to extract all the data

I have data that looks like the image above. Could anyone please help me what command to use to extract all the data? I did it manually using the code below. But, I have another data that is up to val(:,:,365), so any help is greatly appreciated.

sla=ncread('cmems_obs-sl_glo_phy-ssh_my_allsat-l4-duacs-0.25deg_P1M-m_1639987960602.nc','sla');
A1=sla(:,:,1)';
A2=sla(:,:,2)';
A3=sla(:,:,3)';
A4=sla(:,:,4)';
A5=sla(:,:,5)';
A6=sla(:,:,6)';
A7=sla(:,:,7)';
A8=sla(:,:,8)';
A9=sla(:,:,9)';
A10=sla(:,:,10)';
A11=sla(:,:,11)';
A12=sla(:,:,12)';
slaData=vertcat(A1,A2,A3,A4,A5,A6,A7,A8,A9,A10,A11,A12);

Just permute the array dimensions.

sla = cat(3,(1:10).',(11:20).',(21:30).',(31:40).'); % smaller example array
size(sla) % 4 columns arranged on dim3

ans = 1×3

10 1 4

% permute
sla = permute(sla,[3 1 2])

sla = 4×10

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40
