String array and Numeric values
显示 更早的评论
Hi,,
I have a String array that contains Names, I want to allow the user to choose a Name to change either by writing the name as a string OR by writing it's index as a number..
So I wrote this code, but it seems faulty.. Can anyone help with this..
Thanks in advance:
clear all
clc
Nums=[1:5]
%NumsStr=num2str(Nums)
for i=1:5
s=input('s= ','s')
s=strtrim(s);
S{i}=(s);
clc
end
S
for i=1:5
tst=input('edit what ','s')
try
res=strmatch(tst,S,'exact')
if((length(res)~=0) && (length(res)<2))
S{res(1)}=input('TEXT_MODE, New String =','s')
else
%NumRes=strmatch(tst,num2str(Nums))
NumRes=find(Nums==tst)
if((length(NumRes)~=0) && (length(NumRes)<2))
S{NumRes(1)}=input('NUMBER_MODE, New String = ','s')
end
end
catch ME
end
end

In your original code, you should change the line after the else statement to:
NumRes=find(Nums==str2num(tst))

% Say your String cell looks like this:
S = {'Ted' 'Jim' 'Nancy'}
% To change by name:
cname = 'ted'; % User wants to change 'Ted'...
cname_new = 'Frank'; % to 'Frank'.
idx = strcmpi(S,cname); % Find 'Ted'
if any(idx)
S{idx} = cname_new; % Change to 'Frank'
end
Now to use an index instead of a name, just let the user enter cname_new and idx.

EDIT In response to your comment:
for ii =1:5
s = input('s= ','s');
S{ii}=strtrim(s);
clc
end
S
for ii = 1:5
tst = input('Edit what string in array? ','s');
idx = strcmpi(S,tst);
if any(idx)
T = input('TEXT_MODE, Enter New String: ','s');
S{idx} = T;
else
idx = str2double(tst);
if ~isnan(idx)
T = input('NUMERIC_MODE, Enter New String: ','s');
S{idx} = T;
end
end
end
S
