Create multiple sub arrays in one line!

Hi everyone, I have the string bellow as input to a function

'(44) (hello)      (good) ()'

the function looks for indices positions of left and right parenthesis...

open = strfind(text, '(');
close = strfind(text, ')');

after that I want to isolate everything inside the parenthesis...

I was hoping there was a fast way of doing this something like:

output = text(open:close);

but it doesn't seem to work does anyone has a clue if this is possible?!

Try this:

str = '(44) (hello)      (good) ()';
out = regexp(str, '(?<=\()\w*(?=\))', 'match')

producing:

out =

  1×3 cell array

    {'44'}    {'hello'}    {'good'}    

See the documentation on regexp (and its friends) for details.

Make appripriate changes to get the result you wannt.

I actually liked this approach, but I wanted people to be able to set their delimiters.

for example:

split_between('[hello] [banana] [56]', '[', ']');

so I went with @Turlough answer.

[Star Strider]

Note that both answers require that the delimiters be specified. Neither will work with unspecified delimiters.

Example —

split_between = @(str,delim1,delim2) regexpi(str, sprintf('(?<=\\%s)\\w*(?=\\%s)',delim1,delim2), 'match');      % Create Anonymous Function

out = split_between('[hello] [banana] [56]', '[', ']')

producing:

out =

  1×3 cell array

    {'hello'}    {'banana'}    {'56'}

as requested.

Woow this is great! thank you ;)

As always, my pleasure!

This is one way to go about it:

a=strsplit(text(text~=' '),{'(',')'})
output=sprintf('%s',a{:})

[Turlough Hughes]

Actually, just realising you could also write:

output=text(text~=' ' | text~='(' | text~=')')
