Hi, I want to compare 2 strings and see if there are messages that are the same. i want to compare de first line with all the others from the other document and put it in to another string. The string are AIS1 19000 X 1 and AIS2 13000 X 1.
I've coded a little bit but i have an error of matrix dimensions must agree.
M_conjunt = [];
M_D_AIS1 = [];
M_D_AIS2 = [];
N=size(AIS1,1)
P=size(AIS2,1)
for i=1:1:N
for j=1:1:P
seq1=AIS1(i);
seq2=AIS2(j);
linia1=convertStringsToChars(seq1);
linia2=convertStringsToChars(seq2);
if AIS1 == AIS2
M_conjunt = [M_conjunt,i];
end
end
end
I do not undestand why do I continue getting this problem

The err is here:
if AIS1 == AIS2 % ERR
% Corrected one:
if AIS1(i) == AIS2(i)
Note that sizes of AIS1 and AIS2 are to match.
