Friends,
I want to compare 2 cell arrays and if all characters are similar I want to generate 1 as output and else 0 as the output. but i could not find a simple compare function for cell arrays. pls help me on this ? Thanks in advance.

if isfield(hund.A)This will not work. I guess you mean:
if isfield(hund, 'A')Then this works:
if isfield(hund, 'A') && hund.A == 1The condition hund.A==1 is evaluated only, if the first condition is true. If the field 'A' does not exist, the 2nd part is not reached. This is called "shortcircuting".
Alternative: Create a function, which replies a default value for not existing fields:
function R = SafeGetField(S, F)if isfield(S, F) R = S.F;else R = [];endendThen:
if isequal(SafeGetField(hund, 'A'), 1)Or:
function T = CompareField(S, F, V)if isfield(S, F) T = isequal(S.F, V);else T = false;endendand in the main code:
if CompareField(hund, 'A', 1)"as you can see in the command window bk(6) equals ak(2)"
Nope. Just looking at some floating point values displayed in the command window (or variable viewer, etc.) is not a valid way to determine their exact values (and hence is not valid to decide if they are equal). Those values are certainly not equal, which you will see when you view them at a higher precision, e.g. dowload this:
"but comparing between them returns logic 0 how is that even possible?"
Simply because the values are not equal. Read these to know why they are not equal:
