Create function with 8 input and 1 output

hello every one

I need to create function with 8 digital input (each input has two state one or zero ) and one output

for more explaination

if all inputs equal to 1 then out put equal to 1.5

if one input equal to 0 then output equal to 2

if two input equal to 0 then out put equal to 3

.

.

.

.

.

if 7 input equal to 0 then output equal to 8

else output equal to 0

First, dont write a function with 8 variables as input. Have ONE variable be a vector of length 8. LEARN TO USE VECTORS AND ARRAYS!

Now the result is trivial. Count the number of elements in the vector that are zero.

fun([0 0 0 0 0 0 0 0])

ans = 0

fun([1 1 1 1 1 1 0 1])

ans = 2

fun([1 1 1 1 1 1 1 1])

ans = 1.5000

fun([1 0 1 0 1 0 1 0])

ans = 5

function out = fun(V)
  outReturns = [0 8 7 6 5 4 3 2 1.5];
  out = outReturns(sum(V) + 1);
end

This matches your stated goal.

exactly I use simulink for my project so I have 8 variable input and one output

so that I should do function to connect it with my simulink project

kindly can you write full code for that in comment

thanks

No. I won't write full code to do your assignment. I'm sorry, but that is your assignment. However, surely you can figure how to take 8 variables, and concatenate them into a vector? And then, could you use what I showed?
