newstring = strrep(orgstring, word1,word2)

strrep 함수는 orgstring에서 word1을 찾아서 word2로 바꾸어 newstring에 저장한다.

예제)

str1 = 'lonesome';

str2 = strrep(str1,'lone', 'awe');

결과 str2 = 'awesome'

STRREP Replace string with another.

MODIFIEDSTR = STRREP(ORIGSTR,OLDSUBSTR,NEWSUBSTR) replaces all

occurrences of the string OLDSUBSTR within string ORIGSTR with the

string NEWSUBSTR.

Notes:

* STRREP accepts input combinations of single strings, strings in

scalar cells, and same-sized cell arrays of strings. If any inputs

are cell arrays, STRREP returns a cell array.

* STRREP does not find empty strings for replacement. That is, when

ORIGSTR and OLDSUBSTR both contain the empty string (''), STRREP does

not replace '' with the contents of NEWSUBSTR.

Examples:

% Example 1: Replace text in a character array.

claim = 'This is a good example';

new_claim = strrep(claim, 'good', 'great')

new_claim =

This is a great example.

% Example 2: Replace text in a cell array.

c_files = {'c:\cookies.m'; ...

'c:\candy.m'; ...

'c:\calories.m'};

d_files = strrep(c_files, 'c:', 'd:')

d_files =

'd:\cookies.m'

'd:\candy.m'

'd:\calories.m'

% Example 3: Replace text in a cell array with values in a second cell

% array.

missing_info = {'Start: __'; ...

'End: __'};

dates = {'01/01/2001'; ...

'12/12/2002'};

complete = strrep(missing_info, '__', dates)

complete =

'Start: 01/01/2001'

'End: 12/12/2002'
