How to find number of different types of blocks?

How to find number of different types of blocks in a system? For example, if I have two terminators, three inputs, and one 'And', and one 'Or', I want to get 4 as an answer. My idea, would be to find all blocks and then go through them in a loop, is there an easier way?

Try this. Note that in your case, "And" and "Or" block are actually the same block type. It is called logical operator block.

f14;
a=find_system('f14','FindAll','on','type','block');
length(unique(get(a,'BlockType')))
