Also you redefined x and y in the loop
there are conditions for x and y but the range is between -1 and 1

Your function f returns nothing. What do you want to calculate in fun2?
I should calculate fun2 when x and y equal 1, the result should be (1+k-j) and I want to put this in the fun2 and so on for other conditions
A
ABC
example:
function f(x,y)
for x =-1:1, y=-1:1, k in 1, j in 0
if x==1 && y==1
println("1+$k-$j")
elseif x==1 && y==-1
println("1-$k+$j")
end
end
end
How I can put "f(x,y)" into " fun2 = sum(3*fun(x,y))
I should calculate "fun2"
it has error now
function f(x,y)
for x =-1:1, y=-1:1, k in 1, j in 0
if x==1 && y==1
println("1+$k-$j")
elseif x==1 && y==-1
println("1-$k+$j")
end
end
end
How I can put "f(x,y)" into " fun2 = sum(3*fun(x,y))
I should calculate "fun2"
it has error now
Is there any way to calculate this program? I mean, another way to write function and put into sum.

And k and j are always fixed?
A
And k and j are always fixed?
yea
AM
Or these are parameters?
A
Or these are parameters?
they have value
AM
So if x=1 and y=1 then the answer is 1
AM
If x =1 and y = -1 the answer is 0
AM
For any other cases what should it return?
A
So if x=1 and y=1 then the answer is 1
just forget this code, that was a typical example. for me is long formula
A
For any other cases what should it return?
nothing
A
For any other cases what should it return?
there are no other cases. I just have 1 and -1
АО
Ok, lets start from the beginning.
We have some function
We have some function
f(x, y) which returns some results for different values of x, y is it correct?A

АО
Are there any other parameters which can influence the result? Or
f(1, 1) is always some fixed value, for example 1?A

АО
Ok.
Now, you want to sum
Now, you want to sum
f(x, y) over some values of x and y, presumably (-1, 1)?АО
If that is correct,
sum(f(x, y) for x in (-1, 1), y in (-1, 1)) can solve the problem?АО
I am using
(-1, 1) here, because -1:1 == [-1, 0, 1] and you said "I just have 1 and -1"
