Say I have a logical vector:
logicVector = logical([1 0 0 0 1 0 0 0]);
How do one convert it to a number?
From the code above the conversion would give 136 assuming it is unsigned and MSB first. Preferably the type would be fixed point. Best would be a function similar to matlabs 'fi'.
address = logicVec2fi(logicVector, false, true, 0); % logicVec2fi(input, signed, MSB, fraction length)
This will be used in simulink for a binary search where I get a boolean from each search-step which forms the index/address of a ram from the HDL Coder toolbox

Thank you for your solutions! I finally found that the bit concat block does what I want when using only one input port.

Ran in:
Well here's one way.
logicVector = logical([1 0 0 0 1 0 0 0]);
sum(2.^(numel(logicVector)-find(logicVector)))
ans = 136
I have no idea if that's the most appropriate for your application. I have no familiarity with using fi or Coder, so I'm just going to stop there.

Thank you for your soluiton! Perhaps this is the only way, but it seems to use unnessesarly heavy computations when a number is represented in binary after the HDL code generation anyways.
