Dear Matlabians
I have one string '14022010_003' and = another
13022010_001
14022010_003
15022010_005
i want to find 14022010_003 in the other string. I try to use find findstr or strfind and it says to me that I need to have same matrix dimensions.
The result i am searching is for the script to give me the number 2 (that this string is in position 2) .Any ideas
Thank you

a = {'13022010_001';'14022010_003';'15022010_005'};
find(strcmp(a,'14022010_003'))
should give you the index where the string is matched...

Try making the input strings as part of a cell array. Then use STRFIND or STRCMP which will return a logical array of comparisons.
a = {'13022010_001';'14022010_003';'15022010_005'};
strcmp(a,'14022010_003')
ans =
0
1
0

[tf, idx] = ismember('14022010_003', cellstr(['13022010_001'; '14022010_003'; '15022010_005']) );

x = '14022010_003'
y = {'13022010_001'
'14022010_003'
'15022010_005'}
find(strcmp(y,x))
Notice the {} and not [] on y.

STRMATCH is very inefficient and will be removed in the near future. STRCMP and STRCNCMP are much faster.
