I have two matrixes, A and B. These are the same size, 7*7.
I checked matrix A for values are between min and max values by this code:
[RowIndex,ColIndex] = find(A>Min & A<=Max);
And then select each correspond member of matrix B by:
temp=B(RowIndex,ColIndex);
But it returns a wrong matrix (for example 20*20).
Please help me to do that.
Thanks a lot.

Yes you can't do that.
B([1 5 6 1], [4 3 7 8])
would return a 4x4 matrix consisting of row 1, 5, 6 and 1 again of B and column 4, 3, 7 and 8 of B.
To do what you want, simply use linear indexing:
index = find(A>Min & A<=Max);
temp = B(index);
