How do I assign an index value to a function output?

Using R2014b. I have a function called within a for loop which returns lots of outputs. I want to assign an index value for each output of the function as the loop runs. Something like:

for ind = 1:n
   [output1(ind),output2(ind), ...] = function(inputs)
end

This doesn't appear to work (results in an error). Is there an easy way to code this without doing:

output1(ind) = output1;
output2(ind) = output2;

for each variable after the function call?

The multiple outputs: are they all scalars and certain to be non-empty? What error message are you seeing with the "for" version?

Indexing into an output argument works without error:

>> for k = 1:3, [R(k),C(k)] = size(ones(1,k));, end
>> R,C
R =
     1     1     1
C =
     1     2     3

If you want help finding your syntax error then you need to actually tell us what the error message is, and show us your code.

Walter, there are multiple types of outputs (numeric, text, could be a cell or not) and they could be empty. Perhaps that is my problem. Stephen, thanks for the example. I see this works in that case. I worked around my problem by recoding the loop within the function itself and returning indexed outputs. Thanks for the answers!

You cannot assign an empty result into an indexed location, not unless you are using {} indexing on a cell array. Also remember that strings are row vectors of characters, not single locations.

You might need

for ind = 1:n
 [output1{ind},output2{ind}, ...] = function(inputs)
end
