I have CA a 1x3 cell array with {3x13 cell} {3x11 cell} {3x11 cell}. Each nested cell have 2x# double arrays.
Example CA{1} =
3×13 cell array
Columns 1 through 7
[2×153 double] [2×154 double] [2×156 double] [2×154 double] [2×156 double] [2×155 double] [2×154 double]
[2×153 double] [2×154 double] [2×156 double] [2×154 double] [2×156 double] [2×155 double] [2×154 double]
[2×153 double] [2×154 double] [2×156 double] [2×154 double] [2×156 double] [2×155 double] [2×154 double]
Columns 8 through 13
[2×151 double] [2×152 double] [2×152 double] [2×154 double] [2×154 double] [2×161 double]
[2×151 double] [2×152 double] [2×152 double] [2×154 double] [2×154 double] [2×161 double]
[2×151 double] [2×152 double] [2×152 double] [2×154 double] [2×154 double] [2×161 double]
I also have 3 individual cell arrays A {1x13 cell}, B {1x11 cell}, C{1x11 cell}. Each cell have 3x# double arrays.
Example A =
1×13 cell array
Columns 1 through 7
[3×153 double] [3×154 double] [3×156 double] [3×154 double] [3×156 double] [3×155 double] [3×154 double]
Columns 8 through 13
[3×151 double] [3×152 double] [3×152 double] [3×154 double] [3×154 double] [3×161 double]
I need to add/insert/concatenate A into each row of CA{1} to create:
CA_5{1} =
Columns 1 through 7
[5×153 double] [5×154 double] [5×156 double] [5×154 double] [5×156 double] [5×155 double] [5×154 double]
[5×153 double] [5×154 double] [5×156 double] [5×154 double] [5×156 double] [5×155 double] [5×154 double]
[5×153 double] [5×154 double] [5×156 double] [5×154 double] [5×156 double] [5×155 double] [5×154 double]
Columns 8 through 13
[5×151 double] [5×152 double] [5×154 double] [5×154 double] [5×161 double]
[5×151 double] [5×152 double] [5×154 double] [5×154 double] [5×161 double]
[5×151 double] [5×152 double] [5×154 double] [5×154 double] [5×161 double]
B corresponds to CA{2} and C to CA{3}.
I tried to use cellfun and arrayfun but I cannot get to re-concatenate into each row.
cellfun(@(x,y) [x;y], CA{1}, A,'uni',1);
Thanks
