MATLAB: If else, for loop, working with character variables

Question

z = Data(1:10,17) %take 10 numerical values into a new table, name of the variable is LOAN

for i = 1:height(z)

if z.LOAN(i)>300000

z.new(i) = 'pass'

else z.new(i) = 'fail'

end

end

So the above is giving me an error: In an assignment A(:) = B, the number of elements in A and B must be the same.

But if I change the above code to the following:

z = Data(1:10,17) %take 10 numerical values into a new table

for i = 1:height(z)

if z.LOAN(i)>300000

z.new(i) = 1

else z.new(i) = 0

end

end

Then the codes work fine. Why is it only working if I put 1/0 rather than pass/fail? How can I solve this? Thanks.

Two questions:

1. Is z.new initialized before you start assigning values to it?

2. Did you try curly braces?

if z.LOAN(i)>300000,
    z.new{i} = 'pass';
else
    z.new{i} = 'fail';
end
