Could somebody please help me?

I am trying to solve the binary integer (0,1) problem by using a function from this link https://www.mathworks.com/matlabcentral/fileexchange/6990-mixed-integer-lp

f represent six possible places where I can put measuring devices.

My f is x1 to x6 = [1 1 1 1 1 1]

My A =

[ 1  1  1  1  1  1;
1  1  1  1  1  1;
1  0  1  1  1  1;
1  0  1  1  1  1;
1  0  1  1  1  1;
0  0  1  1  1  1]
Lb [0 0 0 0 0 0] and ub [1 1 1 1 1 1 ]
M = [1 1 1 1 1 1]
B = [3 3 3 3 3 3]

And e I left the same as in example. For answer I get

However, I would like to get binary answers that will give me information about where to put measuring devices considering given constrains.

What is "B"? There is "b" as input but not upper case. Your matrix A has duplicated row, meaning you put redundancy in the constraints, thus the problem doesn't seem to be well formulated to me.

If "B" is "b", the solutions are simply peak 3 random positions among 6.

在 MATLAB Online 中打开

If you want to get binary output there should be a possibility to add integer constraints for x(1)...x(6). In combination with lower and upper bounds of 0 and 1 for all x, you would get what you want.

In the function you use this is done by defining vector M containing the indices of integer constrained variables.

M = 1:6;

If you have access to Optimization Toolbox you could also use intlinprog for this purpose.

Also follow the comments given above.
