hello my problem is that i have 11 value for any variable suppose i=1:11 and have another variable suppose b=2:12 also has 11 values now my question is that i want to find out value for i=1 for z=i*b total 11 values and for i=2 another 11 value of z and so on how i can use nested loop

It's not clear what you want. Please give an example with 2 11-element arrays, a and b, and what output(s) you want.

Yes, and all of the Answers so far give you that.

try this:
z = zeros(11,11);
for a=1:11
for b=2:12
z(a,b)=a*b;
end
end
z(:,1)=[];

You declare z as 11 x 11, but then you use it as 11 x 12.
Because of the way MATLAB handles assignments to non-existant locations, this will work, but it does indicate a logic fault on your part.

Z = zeors(11,11);
for i=1:11
for b=2:12
z=i*b;
end
end

You would need to change the assignment to be
z(i,b-1) = i * b;

If the number you're multiplying by is a fractional number, like 0.1 or 0.11 then you'll have to separate your index from your number, like I think you originally had in your message where you had a and b instead of i and b. You could just make the loop index from 1 to 11 and then create the array index from it like arrayIndex = i / 10 and then use arrayIndex in z() or wherever.

z = bsxfun(@times, i(:), b);

Provided "i" is not complex, which it normally is ;-)
