k = findstr( str1,str2 ) searches the longer of the two input arguments for any occurrences of the shorter argument and returns the starting index of each occurrence. If it finds no occurrences, then findstr returns the empty array, [] . The input arguments str1 and str2 can be character vectors or string scalars.
How do I extract a character from a string in MATLAB?
Description. newStr = extract( str , pat ) returns any substrings in str that match the pattern specified by pat . If str is a string array or a cell array of character vectors, then the function extracts substrings from each element of str . If pat is an array, then the function matches against multiple patterns.
