hey everyone,

i want to evaluate the elements of a 100x100 matrix, if the results are in a certain Boundary Condition. From this i want to create a matrix filled with bools, that symbolize if the B.C. were fulfilled or not. is there something i can do?

th reason for this is that i am vektorizing the whole process, and i need to keep the data of previous matrices.

Unfortunately you did not mention which kind of boundary conditions you want to apply. Then a guess:

M  = rand(100, 100);
BC = (M > 0.2) & (M < 0.8);

the b.c. are arbitrary (in my case its almost as you guessed, i need to compare the emissivity of a surface) i just did not know how to do it ;) but this should work.
