MATLAB: How to call a variable that belong to the result of a for looping

axesfor loopguide

I write the listing as a function so that i can call it in main (function plate = crop (f)) in one of axes GUIDE, i want to show the result of a for looping *actually this -for looping- is include in another -for looping- but i just write the one that had the variable
    for n=1:2:length(line2)        In=imcrop(Ik,[line2(n) 1 line2(n+1)-line2(n) bar1]);        subplot(1,length(line2)/2,kk);        kk=kk+1;    end
in axes, i want to show the In variable. I write as plate=In but it said Undefined function or variable "In"

image(In);
