txt1=[{'a'},{'b'},{'c'}];
txt1=txt1(:);
data=[{'a'},{'b'}];
data=data(:);
[row,col] = find(txt1==data)
%it gives

Replace
txt1==data
by
ismember( txt1, data )
and see documentation of ismember

You can also do:
txt1=[{'a'},{'b'},{'c'}];
txt1=txt1(:);
data=[{'a'},{'b'}];
data=data(:);
idx = getnameidx(txt1,data)
idx =
1 2

[mdata,mtext,mraw]=xlsread('o.xlsx');
L=length(mraw);
[D,T,R]=xlsread('Ori.xlsx');
l=length(R);
for i=1:339
A(i)=mraw(i);
end
for j=1: 63314
B(j)=R(j);
end
for i=1:339
for j=1: 63314
if B(j)==A(i)
xlswrite('gotermofO.xlsx',B(j),'A1');
end
end
end

if isequal(B(j), A(i))
This makes no assumptions about the data types: it should work whether the cells are strings or numbers.
Caution: length() is the largest dimension, not the first dimension. Your mraw is generally going to be a 2D array, not a vector.
For efficiency you could be using
A = mraw(1:339);
B = R(1:53314);
Are you sure that you only want a single cell output into the spreadsheet ? Your code overwrites cell A1 each time it finds a match.
Your matching code could be much more efficient if your cells are all numeric or are all strings: in that case you could use ismember(B, A) to do the matching "in bulk"
