IndexingProblem

I have a macro that has an indexing problem.

CartridgeID

i = 1,length(allData);
        Cart_ID(i) = allData(i).CartridgeID;
 end

allData is a struct which contains allData(1,1).CartridgeID which is a 24 digit integer

An attempt to execute the above results in:

i =

     1

Subscripted assignment dimension mismatch.

>>

Obviously an indexing problem, but I can't seem to find a solution.

Without a loop:

Card_ID = [allData.CartridgeID]

With a loop, you will need a "for" statement such as

for i = 1 : length(allData)

Notice the colon instead of comma, and notice the "for". The code you had assigns 1 to i, displays the result, calculates length(allData) and throws away the result of that calculation.

How did you manage to get a 24 digit integer? The maximum integer for uint64 is only 20 digits. Perhaps the value is not really a 24 digit integer, but is instead (e.g.) a string? If it is then you need to store it to multiple output locations:

for i = 1 : length(allData)
  Cart_ID(i,:) = allData(i).CartridgeID;
end
