I have two arrays which I would like to compare with each other.

eg. A = [4.1,5.2,7.1] B = [1,2,3,4,5,6,7,8]

I want to be able to say that the following match 4.1->4, 5.2->5, 7.1->7 and then show it in a different array like C = [0,0,0,1,1,1,0]

I have been trying to use For loops but havent managed to solve it as yet. Any suggestions would be useful

*edit

I cannot use a Matlab function block as I need to use it with TargetLink later.

Thanks, Dhruv

I guess thats the range. Values between 0 and 2.3 are mapped to 1 and so. However its not clear what hapens with values equal to 2.3. Are those values mapped to 1 or 2?

在 MATLAB Online 中打开

A = [4.1,5.2,7.1];
B = [1,2,3,45,6,7,8];
out=zeros(size(B));
out(fix(A))=1

Is a Look-Up-Table supported? If so, this would be what you need together with a For Itterator Subystem.

I have the possibility of using a Matlab embedded block inside a Stateflow chart.. though I have never used Stateflow.. could you think of it as a possibility to be used in such a case?
