Hi,
If i have a series of tables such as AX1, AX2,,,,,AX10.
And i want to extract element B from each AX sereis and save it in a new table.
I tried the following idea, but failed:
new_var=zeros(10,1);
for i=1:10;
new_var(i,1)=AZ'i'(5,1);
end;
But it did not work.
can someone help.
Thanks.

My solution
A1 = table(1,2);
A2 = table(1,2);
A = {A1 A2};
for i = 1:2
AA = A{i};
new_var(i,1) = AA(5,1);
end

Hi, can you help me check this code:
Tjp={T1 T2 T3 T4 T5 T6 T7 T8 T9 T10 T11 T12 T13 T14 T15};
n4=200;
for i=1:n2
for j=1:n4
TT1=Tjp{i};
if TT1(j,1) == "David"
jpmorgan(1,Q22016)=str2double(TT1(j,3));
end
end
end
But i always gives me this warning: Undefined operator '==' for input arguments of type 'table'.
Thanks.

You can compare number using == operator
Use strcmp for string
if strcmp(TT1(j,1), "David")
