Scilab Help >> Strings > strsubst

Calling Sequence

string_out = strsubst(string_in, searchStr, replaceStr, [flag])

a character string. The string to search in string_in.


a character string. The replacement string.


a matrix of character strings. The result of the substitution on searchStr by replaceStr in string_in.


a character ("r" for regular expression).


The strsubst function replaces all occurrences of searchStr in string_in by replaceStr.

When using the forth parameter "r", the searchStr should be a string of regular expression. And then strsubst is going to match it with string_in and replace according to the regular expression rules.


strsubst('SCI/demos/scicos','/',' ')
strsubst('2' ,'/2(]*)?$\1/' ,'0','r')
