Hello,
I have a program that produces a very large string array, and I would like to be able to open it in Notepad++. I tried going into Notepad++ to open my file, but when it opened, it looked like gibberish. How can I convert my matlab string array so I can open it in Notepad++?
Thank you

format long
N=input('Enter maximum distance (km) between locations:');
% LLL=table2array(LLL);
% MLL=table2array(MLL);
% MID=table2array(MID);
% LID=table2array(LID);
sizeM=size(MLL);
lengthM=sizeM(1,1);%gives the number of rows in the mindat_LatLong matrix.
sizeU=size(LLL);
lengthU=sizeU(1,1);%gives the number of rows in the UniqueID_LatLong matrix.
p=1;%index variable used to track the row in the mindat_LatLong matrix.
m=1;%index variable used to assign MindID_number to the given UniqueID_LatLong.
v=[];%open matrix for storing mindat id numbers
Results=strings(lengthU,2);
n=1;
z=[];%open matrix for storing distances.
for x=1:lengthU
while p<=lengthM
d=2*6370.997*asin(((sin(((LLL(x,1))-(MLL(p,1)))/2))^2+cos(LLL(x,1))*cos(MLL(p,1))*(sin((LLL(x,2)-MLL(p,2))/2))^2)^0.5);
if 0<d && d<=N
v(1,m)=MID(p,1); %this creates a vector of MindatID numbers.
z(1,p)=d; %this creates a vector of distances.
elseif d==0
v(1,m)=MID(p,1); %this creates a vector of MindatID numbers.
z(1,p)=-5;
else
end
p=p+1;
m=m+1;
end
v(v==0)=[];
z(z==0)=[];
if isempty(v)==0; %if the vector is not empty...
m=min(z);%this finds the minimum distance.
ans = find(z==m);%this givs the column in z than contains m.
index=v(1,ans);%this matches the smallest distance to the corresponding mindatID.
index=mat2str(index);
Str = sprintf('%.0f,' , v);%this separates the values in the string with a comma
Str = Str(1:end-1);
string=[LID(x,1) Str index];
Results(n,1:3)=string;
n=n+1;
end
p=1;
m=1;
z=[];
v=[];
end
Results = rmmissing(Results);

What's all this? Did you see any of the the compact Answers below?

This creates a textfile, which notepadd++ opens.
v1=str(:,1);
v2=str(:,2);
v3=str(:,3);
T = table( v1,v2,v3 );
writetable( T, 'str.csv' )
as does
T = table( str(:,1),str(:,2),str(:,3) );
writetable( T, 'str.csv' )
however, this throws an error
>> writetable( table( str ), 'str.csv' )
Error using writetable (line 142)
Unable to perform assignment because the left and right sides have a different number of
elements.
Better control of the format
%%
cac = str2cell( str );
fid = fopen( 'h:\m\cssm\str.csv', 'w' );
fprintf( fid, '%-24s %-24s %-24s\n', cac{:} );
fclose( fid );
Where (OCR and cleaning)
%%
str = [

I tried using the code below, and it worked in Matlab without an error, but when I opened the file 'str.csv', the values were messed up (see picture below)
Thank you
v1=str(:,1);
v2=str(:,2);
v3=str(:,3);
T = table( v1,v2,v3 );
writetable( T, 'str.csv' )

I figured it out! I just changed the 'str.csv' to 'str.txt' and it fixed the issue. This is exactly what I need, thank you!

Are you using %s instead of %f? Try this - it works!
