Remove simultaneously several substrings in a string

Question

0 个投票

Hi, I have a string

A = "159 (51,1%) 13 (4,2%) 139 (44,7%)";

and I would need to remove all the numbers among brackets (and brackets included!). My goal is to get this new string:

A = "159 13 139";

Any idea ?

I tried this, but it is not working:

>> strtok(A,'()')
ans = 
    "159 "

hello

try this

A = "159 (51,1%) 13 (4,2%) 139 (44,7%)";
B = split(A,' ');
B(contains(B,'(')) = [];
B = join(B,' ');

Many thanks, it work very well!

...Just for fun and curiosity, I also tried textscan with your solution..

B = textscan(A,'%s','Delimiter',' ')';
B{:}(contains(B{:},'(')) = []
B = join(B{:},' ')

which gives:

B =
  1×1 cell array
    {'159 13 139'}
