Take a look at the function regexp() http://www.mathworks.com/help/matlab/ref/regexp.html and with the input like the example below you get both the real and complex return

txt = '1+2i'
regexp(txt,'\w*i*\w*','match')

however read a bit more about regexp as depending on how people type it in you get different answers.
