Comparing elements of matrix of different Sizes dimension in Matlab

Can anybody help me to find out the method to compare the elements of different sized matrix in Matlab ?

I have one matrix A (100×10) with random elements.

The second array has some of elements which are in matrix B (1×10) with random elements.

Let's say element of matrix A(i,j) and B(i,j) is element of B.

So I want to compare B(i_1,j_1) is equal A(i_1,j_1; i_2,j_1; i_3,j_1;.....; i_100_j_1) in these two matrices, i.e, we need to compare first row, first column of matrix B and all row, first column of matrix A.

If they are equal - 1, if not equal - 0. And they will be new matrix C.

The elements are numbers not strings.

What function can i use in this case if I wanna again compare A and B1 (Like B) is 10x1 matrix too ? Perhaps i will add B2, B3..and so on. plz help me. Thanks! Regards, Kyaw Kyaw

Are they integers or floating point? See the FAQ: http://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F

Some are integers and some are floating point.

A=[1 2 3;4 5 6;7 8 9;1 0 1]
B=[1 3 2]
C=bsxfun(@eq,a,b)

For floating point numbers look at Analyst link

Thanks! What function can i use in this case if I wanna again compare A and B1 (Like B) ? Perhaps i will add B2, B3..and so on....

eg: B1=[3 2 1], B3=[4 2 1]

Use the same function. What is the problem with that?

[Azzi Abdelmalek]

Or use

a=[1 2 3;4 5 6;7 8 9;1 0 1]
b=[1 3 2;4 2 1]
[n,m]=size(b)
c=reshape(b',1,m,n)
out=bsxfun(@eq,a,c)

Thank you very much!
