hi all,
i want to replace some old string with new one. i can do in multiple strrep as below:
newChr = strrep(strrep(strrep(strrep(f, 'old', 'wana'), ...
'old1', 'wana1'), ...
'old2','wana2'), ...
'old3','wana3')
but it not convenient to replace 300++ new word. i try to do for loop as below, but dont have any idea to do it. Below my for loop code, anyone can helpme to automate this thing? for now, im still replace using the above methods. thanks
numLines = length(TestInstanceold);
for k = 1:numLines
filename = 'a.txt';
fid = fopen(filename,'r');
f=fread(fid,'*char')';
fclose(fid);
f= strrep(f, TestInstanceold(k,1), TestInstanceold(k,1))
end

MATLAB is designed to work neatly and efficiently with arrays. Rather than doing things one-at-a-time like that, you should be using arrays. For example:
A = "title: the cat in the hat";
old = [ "the", "cat", "in", "hat"];
new = ["seven","brides","for","brothers"];
Method one: REPLACE():
Z = replace(A,old,new)
Method two: REGEXPREP():
B = regexprep(A,old,new)
Method three: STRREP() in a loop:
C = A;
for k = 1:numel(old)
C = strrep(C,old{k},new{k});
end
display(C)
