find strings between using regexp

I want to find all string inside of [ ], for example, I expect to get three results '1ac', 'd2' and 'k3' for following string

'[1ac][d2][k3]'

However, when I use

regexp('[1ac][d2][k3]','(?<=\[).+(?=\])','match')

I will get '1ac][d2][k3'.

How can I get three results '1ac', 'd2' and 'k3' instead?

Use extractBetween instead.

str = '[1ac][d2][k3]'

str = '[1ac][d2][k3]'

newStr = extractBetween(str,"[","]") 

newStr = 3x1 cell array
    {'1ac'}
    {'d2' }
    {'k3' }

Thanks Cris, this function is easy to use
